Obviously, you must have PostgreSQL installed and running, and Tcl/Tk on your system before you can use PgAccess.
PgAccess is an "open source" application. The source code is available to the user, and may be modified by the user. The user can fix a bug, or change the way a function operates. You may not want to get that involved with the programming, but you have the option to do so. If you feel you have made an improvement to the program, you are encouraged to share it with other users.
If you are not familiar with how open source software can be altered and redistributed, please read this.

This HOWO-TO make PgAccess working under Irix
is written by Stuart Rison These are the steps that I had to follow to get pgaccess to run on an
INDIGO2 running postgreSQL 6.3.2 under IRIX 5.3. I make no guarantee whatsoever
that the same step will work for others but at least it should point you
in the right direction. Also, I am a biologist by training so I only got
pgaccess working by fudging (that is, trial and error) this means that
some of the steps may be unnecessary (e.g. compiling $postgreSQL_source/src/interfaces/libpgtcl
as both a shared and static library) and they certainly haven't been optimised
(I know nothing about compiler switches etc.). 1) Requirements: You will need: 2) Installation: a) tcl/tk: You must first install tcl and then tk (in that order). I just used
./configure, no switches and gmake. Their installation should be trouble
free. Then you must move headers and libraries to the right places so: Header files: both tcl and tk have a header file (tcl.h and tk.h). The
tcl.h file is in $tcl_source_dir/generic and the tk.h file is in $tk_source_dir/generic;
both should be copied to /usr/local/include. Libraries: compilation (with cc) of tcl and tk yield libraries libtcl8.0.a
and libtk8.0.a in $source_dir/unix. Both should be copied to /usr/local/lib. b) postgreSQL: Make sure you have a fully patched postgreSQL source. If your ./configure
says it can't load 'IRIX' settings then you most probably will need to
patch ./configure. Configure using ./configure with the following switches: ./configure
--with-includes=/usr/local/include --with-libraries=/usr/local/lib --with-tcl [this and previous line as
one] Then make, make install as usual c) Compiling libpgtcl: The source for libpgtcl is in $postgreSQL_directory/src/interfaces/libpgsql. I do this twice. Once with just gmake. This produces a static library
libpgtcl.a which I leave where it is (I don't know what to do with it but
it may just come in handy). The I modify Makefile manually with a text
editor. Essentially I modify two line: before: # Shared library stuff install-shlib-dep := shlib := after: # Shared library stuff install-shlib-dep := install-shlib shlib := libpgtcl.so.1 Then gmake -f Makefile_modified. This creates two shared (.so) libraries:
libpgtcl.so and libpgtcl.so.1. I can't tell the difference between them
so I copied them both to /usr/lib/. d) running pgaccess: Uncompress pgaccess (usually with gunzip and tar). So long as 'wish'
(a binary produced when compiling tk8.0) is somewhere in your path, you
should be able to run pgaccess with: wish -f $pgaccess_dir/pgaccess.tcl [postgreSQL_database_name] e) et voila! 3) Concluding remarks: As I stated at the start of this document, following the procedure indicated
above worked for me. I am sure, however, that a few of the steps are unnecessary/non-optimised/stupid
etc. If any Unix (IRIX) boffin is reading this and you spot anything you
would like to comment/correct etc. please e-mail me (stuart@ludwig.ucl.ac.uk).
Also, if you just have questions and think I might help, please contact
me at the same e-mail. Finally, I can accept no responsibility if these steps don't work for
you or if it all goes horribly wrong and you 'damage' your computer trying
them. Let common sense prevail! Good luck Stuart Rison LICR University College London London W1P 8BTHow to get help with PgAccess

Error connecting database
Connection to database failed
connectDB() failed: Is the
postmaster running and
accepting TCP/IP (with -i)
connections at 'localhost' on
port '5432'?
This usually occurs because the "postmaster" (the postgreSQL backend) was not
started with the -i option. Usually just adding -i to
the command line that starts the postmaster and restarting will fix this.
ftp://ftp.flex.ro/pub/pgaccess
is one place that you can download precompiled libpgtcl libraries for
PgAccess.
One solution was proposed by H.P.Heidinger ( hph@hphbbs.ruhr.de) and
is very simple.
If you look in the file pgaccess.tcl, you will find the fonts declared in
this manner:
$ grep -e '-font' -i pgaccess.tcl
-font -Adobe-Helvetica-Medium-R-Normal-*-*-120-*-*-*-*-iso8859-1
That is, inserting an asterisk between the first pair of hyphens, and changing
the final two asterisks to iso8859 and 1
respectively.
You can alter the source code by running the following script :
#!/bin/sh
The final version of PgAccess (1.0) will let the user decide what fonts
will be used through a "preferences" dialog window.
In the procedure wpg_exec change the following line:
set pgsql(errmsg) [pg_result $pgsql(res) -error]
to this:
set pgsql(errmsg) "NO ERROR INFORMATION SUPPLIED"
and the program will work. The only disadvantage is that with some error
conditions, you will not get the appropriate error message from libpgtcl.

The home page will contain instructions on which files to download for your
operating system. Download the file to a directory where the program will
eventually reside (see below).
pgaccess-n.nn.tar.gz
Note that "n.nn" will be the version number in an actual file.
First decide where you want to have the program. A typical location on UNIX
systems is /usr/local/src/<name>, where <name> is the name of
the program. To use this location, download or move the "tar.gz" file to the
directory /usr/local/src. Change to that directory, and
uncompress the file with the command:
tar -zxvf pgaccess-n.nn.tar.gz
You should see the files listed as they are uncompressed and placed in the new
directory, and now have a directory named:
/usr/local/src/pgaccess
In that directory will be all of the files that were packaged in the downloaded
file. When you have PgAccess working, you can delete the file with the ".tar"
or ".tar.gz" extension.
echo $PATH
Usually the directory /usr/local/bin will be in your PATH, and that
is a fairly common place to put programs like PgAccess. Other common
directories in the PATH are /usr/bin and /usr/sbin.
Simply move the file "pgaccess.tcl" to the directory where you want it.
pgaccess.tcl
If the program has been placed in a directory listed in the PATH, the PgAccess
window should appear.
pgaccess name "PgAccess"
This assumes that you have an "Applications" sub-menu. You may prefer
"Programs" or some other place. Also, you will have to create the
"mini-pgaccess.xpm" icon if you want it to appear. You can edit an existing
icon from the /usr/share/icons/mini directory in XPaint and rename
it. When you next start an X-Windows session, there should be a "PgAccess" item
on the menu that you have chosen. Clicking on this item should start
PgAccess.libpgtcl not found
PgAccess requires a library of functions named libpgtcl. This
should be available with the postgreSQL distribution, and is usually placed in
the correct location when installing postgreSQL. First check that there is a
file named libpgtcl.so (perhaps with a number appended - or
libpgtcl.dll on Windows systems) on your
system. If not, you will have to download and perhaps compile this library.Locale specific characters
This problem occurs with some special characters used in different
countries because PgAccess did not use fonts with `-ISO8859-1' encoding.

How to get PgAccess
If you have this HTML help system, you have probably already downloaded
PgAccess. If not, or you wish to download the latest version, it is available
from the URL:How to uncompress PgAccess
PgAccess, like most applications available for download, is usually downloaded
in compressed format to save download time. You must uncompress these files in
order to use the application.UNIX (Linux, BSD, IRIX, Solaris, etc.)
The files will be compressed using "gzip" and packaged using "tar", and have
filenames like this:Windows
The files will be compressed so that "WinZip" will uncompress the package. Just
open the file with "WinZip" and the program files will be extracted.Putting PgAccess where it will be found
UNIX
In order to run PgAccess easily, the program file "pgaccess.tcl" should be in a
location on the "PATH" of the system. You can find out what the PATH is by
entering:
/sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin:/usr/local/bin:./:/usr/local/pgsql/bin
Windows
You will usually link PgAccess to an icon, so just specify the full path to the
program when you create the icon.
Starting PgAccess
The easiest way to start PgAccess is to simply invoke the program by name:Starting from a menu
Most users will want to link the program to a menu or icon so that it can be
started using the mouse or other pointing device. Here is a method that will
work on most Linux X-Windows systems. Create a file named "pgaccess" in the directory
/etc/X11/wmconfig with the following contents:
pgaccess description "postgreSQL frontend"
pgaccess mini-icon "mini-pgaccess.xpm"
pgaccess group "Applications"
pgaccess exec "pgaccess.tcl &"
