PostgreSQL. This hash function replaces the one used by hash indexes and
the catalog cache. Hash joins use a different, relatively poor-quality
hash function, but I'll fix that later.
As suggested by Tom Lane, this patch also changes the size of the fixed
hash table used by the catalog cache to be a power-of-2 (instead of a
prime: I chose 256 instead of 257). This allows the catcache to lookup
hash buckets using a simple bitmask. This should improve the performance
of the catalog cache slightly, since the previous method (modulo a
prime) was slow.
In my tests, this improves the performance of hash indexes by between 4%
and 8%; the performance when using btree indexes or seqscans is
basically unchanged.

- domain.patch -> source patch against pgsql in cvs
- drop_domain.sgml and create_domain.sgml -> New doc/src/sgml/ref docs
- dominfo.txt -> basic domain related queries I used for testing
[ ADDED TO /doc]
Enables domains of array elements -> CREATE DOMAIN dom int4[3][2];
Uses a typbasetype column to describe the origin of the domain.
Copies data to attnotnull rather than processing in execMain().
Some documentation differences from earlier.
If this is approved, I'll start working on pg_dump, and a \dD <domain>
option in psql, and regression tests. I don't really feel like doing
those until the system table structure settles for pg_type.
CHECKS when added, will also be copied to to the table attributes. FK
Constraints (if I ever figure out how) will be done similarly. Both
will lbe handled by MergeDomainAttributes() which is called shortly
before MergeAttributes().

o Change all current CVS messages of NOTICE to WARNING. We were going
to do this just before 7.3 beta but it has to be done now, as you will
see below.
o Change current INFO messages that should be controlled by
client_min_messages to NOTICE.
o Force remaining INFO messages, like from EXPLAIN, VACUUM VERBOSE, etc.
to always go to the client.
o Remove INFO from the client_min_messages options and add NOTICE.
Seems we do need three non-ERROR elog levels to handle the various
behaviors we need for these messages.
Regression passed.
parts o f postgresql. The jdbc drivers are never compiled with debugging
support. This p atch make sure that debugging information is added to
the jdbc jar when the --en able-debug is added. This was usefull for me
for debugging some java jdbc poolin g objects but this might perhaps be
usefull for other people too?
