Requirements

In general, a modern Unix-compatible platform should be able to run
PostgreSQL. The platforms that had received specific testing at the time of
release are listed in the Section called Supported Platforms below. In the
"doc" subdirectory of the distribution there are several platform-specific
FAQ documents you might wish to consult if you are having trouble.

The following prerequisites exist for building PostgreSQL:

   * GNU make is required; other make programs will *not* work. GNU make is
     often installed under the name "gmake"; this document will always refer
     to it by that name. (On some systems GNU make is the default tool with
     the name "make".) To test for GNU make enter

     gmake --version

     It is recommended to use version 3.76.1 or later.

   * You need an ISO/ANSI C compiler. Recent versions of GCC are
     recommendable, but PostgreSQL is known to build with a wide variety of
     compilers from different vendors.

   * gzip is needed to unpack the distribution in the first place. If you
     are reading this, you probably already got past that hurdle.

   * The GNU Readline library (for comfortable line editing and command
     history retrieval) will automatically be used if found. You might wish
     to install it before proceeding, but it is not essential. (On NetBSD,
     the "libedit" library is readline-compatible and is used if
     "libreadline" is not found.)

   * GNU Flex and Bison are needed to build from scratch, but they are *not*
     required when building from a released source package because
     pre-generated output files are included in released packages. You will
     need these programs only when building from a CVS tree or if you
     changed the actual scanner and parser definition files. If you need
     them, be sure to get Flex 2.5.4 or later and Bison 1.28 or later. Other
     yacc programs can sometimes be used, but doing so requires extra effort
     and is not recommended. Other lex programs will definitely not work.

   * To build on Windows NT or Windows 2000 you need the Cygwin and cygipc
     packages. See the file "doc/FAQ_MSWIN" for details.

If you need to get a GNU package, you can find it at your local GNU mirror
site (see http://www.gnu.org/order/ftp.html for a list) or at
ftp://ftp.gnu.org/gnu/.

Also check that you have sufficient disk space. You will need about 30 MB
for the source tree during compilation and about 10 MB for the installation
directory. An empty database cluster takes about 20 MB, databases take about
five times the amount of space that a flat text file with the same data
would take. If you are going to run the regression tests you will
temporarily need an extra 20 MB. Use the "df" command to check for disk
space.

  ------------------------------------------------------------------------

If You Are Upgrading

The internal data storage format changes with new releases of PostgreSQL.
Therefore, if you are upgrading an existing installation that does not have
a version number "7.2.x", you must back up and restore your data as shown
here. These instructions assume that your existing installation is under the
"/usr/local/pgsql" directory, and that the data area is in
"/usr/local/pgsql/data". Substitute your paths appropriately.

  1. Make sure that your database is not updated during or after the backup.
     This does not affect the integrity of the backup, but the changed data
     would of course not be included. If necessary, edit the permissions in
     the file "/usr/local/pgsql/data/pg_hba.conf" (or equivalent) to
     disallow access from everyone except you.

  2. To dump your database installation, type:

     pg_dumpall > outputfile

     If you need to preserve OIDs (such as when using them as foreign keys),
     then use the "-o" option when running "pg_dumpall".

     "pg_dumpall" does not save large objects. Check the Administrator's
     Guide if you need to do this.

     Make sure that you use the "pg_dumpall" command from the version you
     are currently running. 7.2's "pg_dumpall" should not be used on older
     databases.

  3. If you are installing the new version at the same location as the old
     one then shut down the old server, at the latest before you install the
     new files:

     kill -INT `cat /usr/local/pgsql/data/postmaster.pid`

     Versions prior to 7.0 do not have this "postmaster.pid" file. If you
     are using such a version you must find out the process id of the server
     yourself, for example by typing "ps ax | grep postmaster", and supply
     it to the "kill" command.

     On systems that have PostgreSQL started at boot time, there is probably
     a start-up file that will accomplish the same thing. For example, on a
     Red Hat Linux system one might find that

     /etc/rc.d/init.d/postgresql stop

     works. Another possibility is "pg_ctl stop".

  4. If you are installing in the same place as the old version then it is
     also a good idea to move the old installation out of the way, in case
     you have trouble and need to revert to it. Use a command like this:

     mv /usr/local/pgsql /usr/local/pgsql.old

After you have installed PostgreSQL 7.2, create a new database directory and
start the new server. Remember that you must execute these commands while
logged in to the special database user account (which you already have if
you are upgrading).

/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data

Finally, restore your data with

/usr/local/pgsql/bin/psql -d template1 -f outputfile

using the *new* psql.

You can also install the new version in parallel with the old one to
decrease the downtime. These topics are discussed at length in the
Administrator's Guide, which you are encouraged to read in any case.

  ------------------------------------------------------------------------

Installation Procedure

  1. Configuration

     The first step of the installation procedure is to configure the source
     tree for your system and choose the options you would like. This is
     done by running the "configure" script. For a default installation
     simply enter

     ./configure

     This script will run a number of tests to guess values for various
     system dependent variables and detect some quirks of your operating
     system, and finally will create several files in the build tree to
     record what it found.

     The default configuration will build the server and utilities, as well
     as all client applications and interfaces that require only a C
     compiler. All files will be installed under "/usr/local/pgsql" by
     default.

     You can customize the build and installation process by supplying one
     or more of the following command line options to "configure":

     --prefix=PREFIX

          Install all files under the directory "PREFIX" instead of
          "/usr/local/pgsql". The actual files will be installed into
          various subdirectories; no files will ever be installed directly
          into the "PREFIX" directory.

          If you have special needs, you can also customize the individual
          subdirectories with the following options.

     --exec-prefix=EXEC-PREFIX

          You can install architecture-dependent files under a different
          prefix, "EXEC-PREFIX", than what "PREFIX" was set to. This can be
          useful to share architecture-independent files between hosts. If
          you omit this, then "EXEC-PREFIX" is set equal to "PREFIX" and
          both architecture-dependent and independent files will be
          installed under the same tree, which is probably what you want.

     --bindir=DIRECTORY

          Specifies the directory for executable programs. The default is
          "EXEC-PREFIX/bin", which normally means "/usr/local/pgsql/bin".

     --datadir=DIRECTORY

          Sets the directory for read-only data files used by the installed
          programs. The default is "PREFIX/share". Note that this has
          nothing to do with where your database files will be placed.

     --sysconfdir=DIRECTORY

          The directory for various configuration files, "PREFIX/etc" by
          default.

     --libdir=DIRECTORY

          The location to install libraries and dynamically loadable
          modules. The default is "EXEC-PREFIX/lib".

     --includedir=DIRECTORY

          The directory for installing C and C++ header files. The default
          is "PREFIX/include".

     --docdir=DIRECTORY

          Documentation files, except "man" pages, will be installed into
          this directory. The default is "PREFIX/doc".

     --mandir=DIRECTORY

          The man pages that come with PostgreSQL will be installed under
          this directory, in their respective "manx" subdirectories. The
          default is "PREFIX/man".

          Note: Care has been taken to make it possible to install
          PostgreSQL into shared installation locations (such as
          "/usr/local/include") without interfering with the namespace
          of the rest of the system. First, the string "/postgresql" is
          automatically appended to datadir, sysconfdir, and docdir,
          unless the fully expanded directory name already contains the
          string "postgres" or "pgsql". For example, if you choose
          "/usr/local" as prefix, the documentation will be installed
          in "/usr/local/doc/postgresql", but if the prefix is
          "/opt/postgres", then it will be in "/opt/postgres/doc".
          Second, the installation layout of the C and C++ header files
          has been reorganized in the 7.2 release. The public header
          files of the client interfaces are installed into includedir
          and are namespace-clean. The internal header files and the
          server header files are installed into private directories
          under includedir. See the Programmer's Guide for information
          about how to get at the header files for each interface.
          Finally, a private subdirectory will also be created, if
          appropriate, under libdir for dynamically loadable modules.

     --with-includes=DIRECTORIES

          "DIRECTORIES" is a colon-separated list of directories that will
          be added to the list the compiler searches for header files. If
          you have optional packages (such as GNU Readline) installed in a
          non-standard location, you have to use this option and probably
          also the corresponding "--with-libraries" option.

          Example: --with-includes=/opt/gnu/include:/usr/sup/include.

     --with-libraries=DIRECTORIES

          "DIRECTORIES" is a colon-separated list of directories to search
          for libraries. You will probably have to use this option (and the
          corresponding "--with-includes" option) if you have packages
          installed in non-standard locations.

          Example: --with-libraries=/opt/gnu/lib:/usr/sup/lib.

     --enable-locale

          Enables locale support. There is a performance penalty associated
          with locale support, but if you are not in an English-speaking
          environment you will most likely need this.

     --enable-recode

          Enables single-byte character set recode support. See the
          Administrator's Guide about this feature.

     --enable-multibyte

          Allows the use of multibyte character encodings (including
          Unicode) and character set encoding conversion. Read the
          Administrator's Guide for details.

          Note that some interfaces (such as Tcl or Java) expect all
          character strings to be in Unicode, so this option will be
          required to correctly support these interfaces.

     --enable-nls[=LANGUAGES]

          Enables Native Language Support (NLS), that is, the ability to
          display a program's messages in a language other than English.
          "LANGUAGES" is a space separated list of codes of the languages
          that you want supported, for example --enable-nls='de fr'. (The
          intersection between your list and the set of actually provided
          translations will be computed automatically.) If you do not
          specify a list, then all available translations are installed.

          To use this option, you will need an implementation of the gettext
          API. Some operating systems have this built-in (e.g., Linux,
          NetBSD, Solaris), for other systems you can download an add-on
          package from here: http://www.postgresql.org/~petere/gettext.html.
          If you are using the gettext implementation in the GNU C library
          then you will additionally need the GNU gettext package for some
          utility programs. For any of the other implementations you will
          not need it.

     --with-pgport=NUMBER

          Set "NUMBER" as the default port number for server and clients.
          The default is 5432. The port can always be changed later on, but
          if you specify it here then both server and clients will have the
          same default compiled in, which can be very convenient. Usually
          the only good reason to select a non-default value is if you
          intend to run multiple PostgreSQL servers on the same machine.

     --with-perl

          Build the Perl interface module. The Perl interface will be
          installed at the usual place for Perl modules (typically under
          "/usr/lib/perl"), so you must have root access to perform the
          installation step (see step 4). You need to have Perl 5 installed
          to use this option.

     --with-python

          Build the Python interface module. You need to have root access to
          be able to install the Python module at its default place
          ("/usr/lib/pythonx.y"). To be able to use this option, you must
          have Python installed and your system needs to support shared
          libraries. If you instead want to build a new complete interpreter
          binary, you will have to do it manually.

     --with-tcl

          Builds components that require Tcl/Tk, which are libpgtcl,
          pgtclsh, pgtksh, PgAccess, and PL/Tcl. But see below about
          "--without-tk".

     --without-tk

          If you specify "--with-tcl" and this option, then programs that
          require Tk (pgtksh and PgAccess) will be excluded.

     --with-tclconfig=DIRECTORY, --with-tkconfig=DIRECTORY

          Tcl/Tk installs the files "tclConfig.sh" and "tkConfig.sh", which
          contain configuration information needed to build modules
          interfacing to Tcl or Tk. These files are normally found
          automatically at their well-known locations, but if you want to
          use a different version of Tcl or Tk you can specify the directory
          in which to find them.

     --with-java

          Build the JDBC driver and associated Java packages. This option
          requires Ant to be installed (as well as a JDK, of course). Refer
          to the JDBC driver documentation in the Programmer's Guide for
          more information.

     --with-krb4[=DIRECTORY], --with-krb5[=DIRECTORY]

          Build with support for Kerberos authentication. You can use either
          Kerberos version 4 or 5, but not both. The "DIRECTORY" argument
          specifies the root directory of the Kerberos installation;
          "/usr/athena" is assumed as default. If the relevant header files
          and libraries are not under a common parent directory, then you
          must use the "--with-includes" and "--with-libraries" options in
          addition to this option. If, on the other hand, the required files
          are in a location that is searched by default (e.g., "/usr/lib"),
          then you can leave off the argument.

          "configure" will check for the required header files and libraries
          to make sure that your Kerberos installation is sufficient before
          proceeding.

     --with-krb-srvnam=NAME

          The name of the Kerberos service principal. postgres is the
          default. There's probably no reason to change this.

     --with-openssl[=DIRECTORY]

          Build with support for SSL (encrypted) connections. This requires
          the OpenSSL package to be installed. The "DIRECTORY" argument
          specifies the root directory of the OpenSSL installation; the
          default is "/usr/local/ssl".

          "configure" will check for the required header files and libraries
          to make sure that your OpenSSL installation is sufficient before
          proceeding.

     --with-pam

          Build with PAM (Pluggable Authentication Modules) support.

     --enable-syslog

          Enables the PostgreSQL server to use the syslog logging facility.
          (Using this option does not mean that you must log with syslog or
          even that it will be done by default, it simply makes it possible
          to turn that option on at run time.)

     --enable-debug

          Compiles all programs and libraries with debugging symbols. This
          means that you can run the programs through a debugger to analyze
          problems. This enlarges the size of the installed executables
          considerably, and on non-GCC compilers it usually also disables
          compiler optimization, causing slowdowns. However, having the
          symbols available is extremely helpful for dealing with any
          problems that may arise. Currently, this option is recommended for
          production installations only if you use GCC. But you should
          always have it on if you are doing development work or running a
          beta version.

     --enable-cassert

          Enables assertion checks in the server, which test for many "can't
          happen" conditions. This is invaluable for code development
          purposes, but the tests slow things down a little. Also, having
          the tests turned on won't necessarily enhance the stability of
          your server! The assertion checks are not categorized for
          severity, and so what might be a relatively harmless bug will
          still lead to server restarts if it triggers an assertion failure.
          Currently, this option is not recommended for production use, but
          you should have it on for development work or when running a beta
          version.

     --enable-depend

          Enables automatic dependency tracking. With this option, the
          makefiles are set up so that all affected object files will be
          rebuilt when any header file is changed. This is useful if you are
          doing development work, but is just wasted overhead if you intend
          only to compile once and install. At present, this option will
          work only if you use GCC.

     If you prefer a C or C++ compiler different from the one "configure"
     picks then you can set the environment variables CC or CXX,
     respectively, to the program of your choice. Similarly, you can
     override the default compiler flags with the CFLAGS and CXXFLAGS
     variables. For example:

     env CC=/opt/bin/gcc CFLAGS='-O2 -pipe' ./configure

  2. Build

     To start the build, type

     gmake

     (Remember to use GNU make.) The build may take anywhere from 5 minutes
     to half an hour depending on your hardware. The last line displayed
     should be

     All of PostgreSQL is successfully made. Ready to install.

  3. Regression Tests

     If you want to test the newly built server before you install it, you
     can run the regression tests at this point. The regression tests are a
     test suite to verify that PostgreSQL runs on your machine in the way
     the developers expected it to. Type

     gmake check

     (This won't work as root; do it as an unprivileged user.) It is
     possible that some tests fail, due to differences in error message
     wording or floating point results. The file "src/test/regress/README"
     and the Administrator's Guide contain detailed information about
     interpreting the test results. You can repeat this test at any later
     time by issuing the same command.

  4. Installing The Files

          Note: If you are upgrading an existing system and are going
          to install the new files over the old ones, then you should
          have backed up your data and shut down the old server by now,
          as explained in the Section called If You Are Upgrading
          above.

     To install PostgreSQL enter

     gmake install

     This will install files into the directories that were specified in
     step 1. Make sure that you have appropriate permissions to write into
     that area. Normally you need to do this step as root. Alternatively,
     you could create the target directories in advance and arrange for
     appropriate permissions to be granted.

     If you built the Perl or Python interfaces and you were not the root
     user when you executed the above command then that part of the
     installation probably failed. In that case you should become the root
     user and then do

     gmake -C src/interfaces/perl5 install
     gmake -C src/interfaces/python install

     If you do not have superuser access you are on your own: you can still
     take the required files and place them in other directories where Perl
     or Python can find them, but how to do that is left as an exercise.

     The standard installation provides only the header files needed for
     client application development. If you plan to do any server-side
     program development (such as custom functions or data types written in
     C), then you may want to install the entire PostgreSQL include tree
     into your target include directory. To do that, enter

     gmake install-all-headers

     This adds a megabyte or two to the installation footprint, and is only
     useful if you don't plan to keep the whole source tree around for
     reference. (If you do, you can just use the source's include directory
     when building server-side software.)

     Client-only installation: If you want to install only the client
     applications and interface libraries, then you can use these commands:

     gmake -C src/bin install
     gmake -C src/include install
     gmake -C src/interfaces install
     gmake -C doc install

     To undo the installation use the command "gmake uninstall". However,
     this will not remove any created directories.

After the installation you can make room by removing the built files from
the source tree with the "gmake clean" command. This will preserve the files
made by the configure program, so that you can rebuild everything with
"gmake" later on. To reset the source tree to the state in which it was
distributed, use "gmake distclean". If you are going to build for several
platforms from the same source tree you must do this and re-configure for
each build.

If you perform a build and then discover that your configure options were
wrong, or if you change anything that configure investigates (for example,
you install GNU Readline), then it's a good idea to do "gmake distclean"
before reconfiguring and rebuilding. Without this, your changes in
configuration choices may not propagate everywhere they need to.

  ------------------------------------------------------------------------

Post-Installation Setup

Shared Libraries

On some systems that have shared libraries (which most systems do) you need
to tell your system how to find the newly installed shared libraries. The
systems on which this is *not* necessary include BSD/OS, FreeBSD, HP-UX,
IRIX, Linux, NetBSD, OpenBSD, Tru64 UNIX (formerly Digital UNIX), and
Solaris.

The method to set the shared library search path varies between platforms,
but the most widely usable method is to set the environment variable
LD_LIBRARY_PATH like so: In Bourne shells ("sh", "ksh", "bash", "zsh")

LD_LIBRARY_PATH=/usr/local/pgsql/lib
export LD_LIBRARY_PATH

or in "csh" or "tcsh"

setenv LD_LIBRARY_PATH /usr/local/pgsql/lib

Replace /usr/local/pgsql/lib with whatever you set "--libdir" to in step 1.
You should put these commands into a shell start-up file such as
"/etc/profile" or "~/.bash_profile". Some good information about the caveats
associated with this method can be found at
http://www.visi.com/~barr/ldpath.html.

On some systems it might be preferable to set the environment variable
LD_RUN_PATH *before* building.

If in doubt, refer to the manual pages of your system (perhaps "ld.so" or
"rld"). If you later on get a message like

psql: error in loading shared libraries
libpq.so.2.1: cannot open shared object file: No such file or directory

then this step was necessary. Simply take care of it then.

If you are on BSD/OS, Linux, or SunOS 4 and you have root access you can run

/sbin/ldconfig /usr/local/pgsql/lib

(or equivalent directory) after installation to enable the run-time linker
to find the shared libraries faster. Refer to the manual page of "ldconfig"
for more information. On FreeBSD, NetBSD, and OpenBSD the command is

/sbin/ldconfig -m /usr/local/pgsql/lib

instead. Other systems are not known to have an equivalent command.

Environment Variables

If you installed into "/usr/local/pgsql" or some other location that is not
searched for programs by default, you need to add "/usr/local/pgsql/bin" (or
whatever you set "--bindir" to in step 1) into your PATH. To do this, add
the following to your shell start-up file, such as "~/.bash_profile" (or
"/etc/profile", if you want it to affect every user):

PATH=/usr/local/pgsql/bin:$PATH

If you are using "csh" or "tcsh", then use this command:

set path = ( /usr/local/pgsql/bin $path )

To enable your system to find the man documentation, you need to add a line
like the following to a shell start-up file:

MANPATH=/usr/local/pgsql/man:$MANPATH

The environment variables PGHOST and PGPORT specify to client applications
the host and port of the database server, overriding the compiled-in
defaults. If you are going to run client applications remotely then it is
convenient if every user that plans to use the database sets PGHOST. This is
not required, however: the settings can be communicated via command line
options to most client programs.

  ------------------------------------------------------------------------

Getting Started

The following is a quick summary of how to get PostgreSQL up and running
once installed. The Administrator's Guide contains more information.

  1. Create a user account for the PostgreSQL server. This is the user the
     server will run as. For production use you should create a separate,
     unprivileged account ("postgres" is commonly used). If you do not have
     root access or just want to play around, your own user account is
     enough, but running the server as root is a security risk and will not
     work.

     adduser postgres

  2. Create a database installation with the "initdb" command. To run
     "initdb" you must be logged in to your PostgreSQL server account. It
     will not work as root.

     root# mkdir /usr/local/pgsql/data
     root# chown postgres /usr/local/pgsql/data
     root# su - postgres
     postgres$ /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data

     The "-D" option specifies the location where the data will be stored.
     You can use any path you want, it does not have to be under the
     installation directory. Just make sure that the server account can
     write to the directory (or create it, if it doesn't already exist)
     before starting "initdb", as illustrated here.

  3. The previous step should have told you how to start up the database
     server. Do so now. The command should look something like

     /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data

     This will start the server in the foreground. To put the server in the
     background use something like

     nohup /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data \
         </dev/null >>server.log 2>&1 </dev/null &

     To stop a server running in the background you can type

     kill `cat /usr/local/pgsql/data/postmaster.pid`

     In order to allow TCP/IP connections (rather than only Unix domain
     socket ones) you need to pass the "-i" option to "postmaster".

  4. Create a database:

     createdb testdb

     Then enter

     psql testdb

     to connect to that database. At the prompt you can enter SQL commands
     and start experimenting.

  ------------------------------------------------------------------------

What Now?

   * The PostgreSQL distribution contains a comprehensive documentation set,
     which you should read sometime. After installation, the documentation
     can be accessed by pointing your browser to
     "/usr/local/pgsql/doc/html/index.html", unless you changed the
     installation directories.

     The Tutorial should be your first reading if you are completely new to
     SQL databases. If you are familiar with database concepts then you want
     to proceed with the Administrator's Guide, which contains information
     about how to set up the database server, database users, and
     authentication.

   * Usually, you will want to modify your computer so that it will
     automatically start the database server whenever it boots. Some
     suggestions for this are in the Administrator's Guide.

   * Run the regression tests against the installed server (using the
     sequential test method). If you didn't run the tests before
     installation, you should definitely do it now. This is also explained
     in the Administrator's Guide.

Supported Platforms

PostgreSQL has been verified by the developer community to work on the
platforms listed below. A supported platform generally means that PostgreSQL
builds and installs according to these instructions and that the regression
tests pass.

     Note: If you are having problems with the installation on a
     supported platform, please write to <pgsql-bugs@postgresql.org> or
     <pgsql-ports@postgresql.org>, not to the people listed here.
