+                                      
    Major changes in this release:
-
+   
    Schemas
-          Schemas allow users to create objects in their own namespace so
-          two people or applications can have tables with the same name.
-          There is also a public schema for shared tables. Table/index
-          creation can be restricted by removing permissions on the
-          public schema.
-
+          Schemas allow users to create objects in separate namespaces,
+          so two people or applications can have tables with the same
+          name. There is also a public schema for shared tables.
+          Table/index creation can be restricted by removing permissions
+          on the public schema.
+          
    Drop Column
           PostgreSQL now supports the ALTER TABLE ... DROP COLUMN
           functionality.
-
+          
    Table Functions
           Functions returning multiple rows and/or multiple columns are
           now much easier to use than before. You can call such a "table
           function" in the SELECT FROM clause, treating its output like a
           table. Also, PL/pgSQL functions can now return sets.
-
+          
    Prepared Queries
           PostgreSQL now supports prepared queries, for improved
           performance.
-
+          
    Dependency Tracking
           PostgreSQL now records object dependencies, which allows
           improvements in many areas. "DROP" statements now take either
           CASCADE or RESTRICT to control whether dependent objects are
           also dropped.
-
+          
    Privileges
           Functions and procedural languages now have privileges, and
           functions can be defined to run with the privileges of their
           creator.
-
+          
    Internationalization
           Both multibyte and locale support are now always enabled.
-
+          
    Logging
           A variety of logging options have been enhanced.
-
+          
    Interfaces
           A large number of interfaces have been moved to
           http://gborg.postgresql.org where they can be developed and
           released independently.
-
+          
    Functions/Identifiers
           By default, functions can now take up to 32 parameters, and
-          identifiers can be up to 63 bytes long.
-     _________________________________________________________________
-
-Migration to version 7.3
-
+          identifiers can be up to 63 bytes long. Also, OPAQUE is now
+          deprecated: there are specific "pseudo-datatypes" to represent
+          each of the former meanings of OPAQUE in function argument and
+          result types.
+     _________________________________________________________________
+   
+                          Migration to version 7.3
+                                      
    A dump/restore using pg_dump is required for those wishing to migrate
    data from any previous release. If your application examines the
    system catalogs, additional changes will be required due to the
    introduction of schemas in 7.3; for more information, see:
    http://www.ca.postgresql.org/docs/momjian/upgrade_tips_7.3.
-
+   
    Observe the following incompatibilities:
-
+   
      * Pre-6.3 clients are no longer supported.
      * "pg_hba.conf" now has a column for the user name and additional
        features. Existing files need to be adjusted.
-     * Several "postgresql.conf" logging parameters have been renamed and
-       improved.
+     * Several "postgresql.conf" logging parameters have been renamed.
      * LIMIT #,# has been disabled; use LIMIT # OFFSET #.
-     * "INSERT" statements with column lists must specify all values;
-       e.g., INSERT INTO tab (col1, col2) VALUES ('val1') is now invalid.
-     * An index is now not automatically created for serial columns.
+     * "INSERT" statements with column lists must specify a value for
+       each specified column. For example, INSERT INTO tab (col1, col2)
+       VALUES ('val1') is now invalid. It's still allowed to supply fewer
+       columns than expected if the "INSERT" does not have a column list.
+     * serial columns are no longer automatically UNIQUE; thus, an index
+       will not automatically be created.
      * A "SET" command inside an aborted transaction is now rolled back.
      * "COPY" no longer considers missing trailing columns to be null.
-       All columns need to be specified.
+       All columns need to be specified. (However, one may achieve a
+       similar effect by specifying a column list in the "COPY" command.)
      * The data type timestamp is now equivalent to timestamp without
-       timezone, instead of timestamp with timezone.
+       time zone, instead of timestamp with time zone.
      * Pre-7.3 databases loaded into 7.3 will not have the new object
        dependencies for serial columns, unique constraints, and foreign
        keys. See the directory "contrib/adddepend/" for a detailed
        description and a script that will add such dependencies.
+     * An empty string ('') is no longer allowed as the input into an
+       integer field. Formerly, it was silently interpreted as 0.

    This release improves PostgreSQL for use in high-volume applications.
-
+   
    Major changes in this release:
-
+   
    VACUUM
           Vacuuming no longer locks tables, thus allowing normal user
           access during the vacuum. A new "VACUUM FULL" command does
           old-style vacuum by locking the table and shrinking the on-disk
           copy of the table.
-
+          
    Transactions
           There is no longer a problem with installations that exceed
           four billion transactions.
-
+          
    OIDs
           OIDs are now optional. Users can now create tables without OIDs
           for cases where OID usage is excessive.
-
+          
    Optimizer
           The system now computes histogram column statistics during
           "ANALYZE", allowing much better optimizer choices.
-
+          
    Security
           A new MD5 encryption option allows more secure storage and
           transfer of passwords. A new Unix-domain socket authentication
           option is available on Linux and BSD systems.
-
+          
    Statistics
           Administrators can use the new table access statistics module
           to get fine-grained information about table and index usage.
-
+          
    Internationalization
           Program and library messages can now be displayed in several
           languages.

    TOAST
           TOAST - Previous releases had a compiled-in row length limit,
           typically 8k - 32k. This limit made storage of long text fields

           We now support outer joins. The UNION/NOT IN workaround for

    Hot backups from pg_dump
           pg_dump takes advantage of the new MVCC features to give a
           consistent database dump/backup while the database stays online
           and available for queries.

           We now have a true numeric data type, with user-specified
           precision.

    Temporary tables
           Temporary tables are guaranteed to have unique names within a
           database session, and are destroyed on session exit.

           ... FOR UPDATE, and an improved LOCK TABLE command.

    Speedups
           We continue to speed up PostgreSQL, thanks to the variety of

    A dump/restore using pg_dump is required for those wishing to migrate
    data from any previous release of PostgreSQL. pg_upgrade can *not* be
    used to upgrade to this release because the on-disk structure of the
    tables has changed compared to previous releases.

    To ensure the actual existence of a row and protect it against
    concurrent updates one must use "SELECT FOR UPDATE" or an appropriate
    "LOCK TABLE" statement. This should be taken into account when porting
    applications from previous releases of PostgreSQL and other
    environments.
-
+   
    Keep the above in mind if you are using "contrib/refint.*" triggers
    for referential integrity. Additional techniques are required now. One
    way is to use "LOCK parent_table IN SHARE ROW EXCLUSIVE MODE" command
    if a transaction is going to update/delete a primary key and use "LOCK
    parent_table IN SHARE MODE" command if a transaction is going to
    update/insert a foreign key.
-

      Note: Note that if you run a transaction in SERIALIZABLE mode then
      you must execute the "LOCK" commands above before execution of any
      DML statement ("SELECT/INSERT/DELETE/UPDATE/FETCH/COPY_TO") in the
      transaction.

    These inconveniences will disappear in the future when the ability to
    read dirty (uncommitted) data (regardless of isolation level) and true
    referential integrity will be implemented.

    permissions now, not based on the underlying tables, so permissions on
    them have to be set separately. Check "/pgsql/interfaces" for some new
    ways to talk to PostgreSQL.

    This is the first release that really required an explanation for
    existing users. In many ways, this was necessary because the new

+                                      
    This is a minor bug-fix release. A dump/reload is not required from
    version 6.1, but is required from any release prior to 6.1. Refer to
    the release notes for 6.1 for more details.

    The regression tests have been adapted and extensively modified for
    the 6.1 release of PostgreSQL.
-
+   
    Three new data types (datetime, timespan, and circle) have been added
    to the native set of PostgreSQL types. Points, boxes, paths, and
    polygons have had their output formats made consistent across the data
    types. The polygon output in misc.out has only been spot-checked for
    correctness relative to the original regression output.

    PostgreSQL 6.1 introduces a new, alternate optimizer which uses

    'off'" and "reset geqo".

    The interpretation of array specifiers (the curly braces around atomic
    values) appears to have changed sometime after the original regression
    tests were generated. The current "./expected/*.out" files reflect
    this new interpretation, which may not be correct!
-

    The float8 regression test fails on at least some platforms. This is
    due to differences in implementations of pow() and exp() and the
    signaling mechanisms used for overflow and underflow conditions.
-
+   
    The "random" results in the random test should cause the "random" test
    to be "failed", since the regression tests are evaluated using a
    simple diff. However, "random" does not seem to produce random results
    on my test machine (Linux/gcc/i686).
