I've attached a simple patch which should improve the performance of
hashname() and reduce the penalty incured when NAMEDATALEN is increased.
I posted this to -hackers a couple days ago, and there haven't been any
major complaints. It passes the regression tests. See -hackers for more
discussion, as well as the suggestion from Tom Lane on which this patch
is based.
Unless anyone sees any problems, please apply for 7.3.

Modify pg_dumpall so that output script uses new OWNER option of CREATE
DATABASE; also make it use SET SESSION AUTHORIZATION commands rather than
\connect commands. This makes it possible to restore databases belonging
to users who do not have CREATEDB privilege. It should also become at
least somewhat feasible to run the restore script under password
authentication --- you'll get one superuser password prompt per database,
rather than a large number of challenges for passwords belonging to
varying unspecified user names.

Add OWNER option to CREATE DATABASE, so superusers can create databases
on behalf of unprivileged users. Also, make '=' optional in CREATE
DATABASE syntax. From Gavin Sherry, with kibitzing and docs by Tom Lane.

The attached patch enables plperl to build under Cygwin. It is
basically yet another BE_DLLLIBS patch with a perl MakeMaker twist. I
tried the patch under Red Hat 7.1 Linux too and I did not observe any
ill effects.

Guard against createdb --location=PGDATA foo; without this, the code

The patch fixes memory leak during creation GiST index on timestamp

This patch fixes the exception thrown to inform the user the method
getColumnClassName(int) is not implemented. This will futher fixes method
ResultSet.getObject(int) since it requires the getColumnClassName(int) method to return the proper java class used to map the database column.

A bunch of changes aimed at reducing backend startup time...
Improve 'pg_internal.init' relcache entry preload mechanism so that it is
safe to use for all system catalogs, and arrange to preload a realistic
set of system-catalog entries instead of only the three nailed-in-cache
indexes that were formerly loaded this way. Fix mechanism for deleting
out-of-date pg_internal.init files: this must be synchronized with transaction
commit, not just done at random times within transactions. Drive it off
relcache invalidation mechanism so that no special-case tests are needed.
Cache additional information in relcache entries for indexes (their pg_index
tuples and index-operator OIDs) to eliminate repeated lookups. Also cache
index opclass info at the per-opclass level to avoid repeated lookups during
relcache load.
Generalize 'systable scan' utilities originally developed by Hiroshi,
move them into genam.c, use in a number of places where there was formerly
ugly code for choosing either heap or index scan. In particular this allows
simplification of the logic that prevents infinite recursion between syscache
and relcache during startup: we can easily switch to heapscans in relcache.c
when and where needed to avoid recursion, so IndexScanOK becomes simpler and
does not need any expensive initialization.
Eliminate useless opening of a heapscan data structure while doing an indexscan
(this saves an mdnblocks call and thus at least one kernel call).

Arrange to call localtime() during postmaster startup. On most Unixen,
the first call of localtime() in a process will read /usr/lib/tztab or
local equivalent. Better to do this once in the postmaster and inherit
the data by fork() than to have to do it during every backend start.

I think it's important that it's actually documented that they can add
primary keys after the fact!
Also, we need to add regression tests for alter table / add primary key
and alter table / drop constraint. These shouldn't be added until 7.3
tho
methinks...
