now has an RTE of its own, and references to its outputs now are Vars
referencing the JOIN RTE, rather than CASE-expressions. This allows
reverse-listing in ruleutils.c to use the correct alias easily, rather
than painfully reverse-engineering the alias namespace as it used to do.
Also, nested FULL JOINs work correctly, because the result of the inner
joins are simple Vars that the planner can cope with. This fixes a bug
reported a couple times now, notably by Tatsuo on 18-Nov-01. The alias
Vars are expanded into COALESCE expressions where needed at the very end
of planning, rather than during parsing.
Also, beginnings of support for showing plan qualifier expressions in
EXPLAIN. There are probably still cases that need work.

1) Put back the error message for SQLError().
2) Change Disallow premature to handle the SELECTed
result.
3) Put back the behavior of AUTUCOMMIT mode change.
4) Fix SQLColumns for ODBC3.0.
5) Improve the handling of variable bookmark in ODBC3.0.
6) Enable Recognize Unique Index Button.
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?

Add PsqlODBC and document ...etc patch.
Eiji Tokuya
(current as of a few hours ago.)
This patch:
1. Adds PG_GETARG_xxx_P_SLICE() macros and associated support routines.
2. Adds routines in src/backend/access/tuptoaster.c for fetching only
necessary chunks of a toasted value. (Modelled on latest changes to
assume chunks are returned in order).
3. Amends text_substr and bytea_substr to use new methods. It now
handles multibyte cases -and should still lead to a performance
improvement in the multibyte case where the substring is near the
beginning of the string.
4. Added new command: ALTER TABLE tabname ALTER COLUMN colname SET
STORAGE {PLAIN | EXTERNAL | EXTENDED | MAIN} to parser and documented in
alter-table.sgml. (NB I used ColId as the item type for the storage
mode string, rather than a new production - I hope this makes sense!).
All this does is sets attstorage for the specified column.
4. AlterTableAlterColumnStatistics is now AlterTableAlterColumnFlags and
handles both statistics and storage (it uses the subtype code to
distinguish). The previous version of my patch also re-arranged other
code in backend/commands/command.c but I have dropped that from this
patch.(I plan to return to it separately).
5. Documented new macros (and also the PG_GETARG_xxx_P_COPY macros) in
xfunc.sgml. ref/alter_table.sgml also contains documentation for ALTER
COLUMN SET STORAGE.
