== Angewandte Patches ==

Peter Eisentraut committed:

- Message format tuning in ecpg.

- Revert updatable views.

- Message fix in pgsql/src/interfaces/ecpg/preproc/parse.pl

- Translation updates.

- In pgsql/src/interfaces/ecpg/preproc/ecpg.c, whitespace fix in
message.

- In ecpg, Make messages consistent with existing ones.

Alvaro Herrera committed:

- Allow extracting and parsing of reloptions from a bare pg_class
tuple, and refactor the relcache code that used to do that. This
allows other callers (particularly autovacuum) to do the same
without necessarily having to open and lock a table.

Magnus Hagander committed:

- In pgsql/src/backend/utils/adt/pg_locale.c, silence compiler
warnings in new win32 locale code when building on mingw. ITAGAKI
Takahiro.

- In pgsql/src/test/regress/pg_regress.c, silence compiler warning on
win32. ITAGAKI Takahiro

- In pgsql/src/bin/pg_ctl/pg_ctl.c, support running as a service on
Windows 7, by not specifying the JOB_OBJECT_UILIMIT_HANDLES flag.
Dave Page & Magnus Hagander

- Go over all OpenSSL return values and make sure we compare them to
the documented API value. The previous code got it right as it's
implemented, but accepted too much/too little compared to the API
documentation. Per comment from Zdenek Kotala.

- In pgsql/src/test/regress/pg_regress.c, change warning-silencing
code not to cast the pointer type, instead casting the value of the
variable later. Per comments from Tom Lane.

Teodor Sigaev committed:

- In pgsql/contrib/tsearch2/tsearch2.c, fix bug with multiple
evaluation of tsearch2 compatibility trigger, trigger data should be
restored. Backpatch only to 8.3 because previous versions don't
have such layer.

- In pgsql/src/backend/tsearch/spell.c, fix incorrect dereferencing of
char* to array's index. Per report from Tommy Gildseth.

Tom Lane committed:

- Replace argument-checking Asserts with regular test-and-elog checks
in all encoding conversion functions. These are not can't-happen
cases because it's possible to create a conversion with the wrong
conversion function for the specified encoding pair. That would
lead to an Assert crash in an Assert-enabled build, or incorrect
conversion otherwise, neither of which is desirable. This would be
a DOS issue if production databases were customarily built with
asserts enabled, but fortunately that's not so. Per an observation
by Heikki. Back-patch to all supported branches.

- Update time zone data files to tzdata release 2009a: introduces
Asia/Kathmandu as the preferred spelling of that zone name, corrects
historical DST information for Switzerland and Cuba.

- In pgsql/doc/src/sgml/release.sgml, update back-branch release
notes.

- Defend against null input in analyze_requires_snapshot(), per report
from Rushabh Lathia. Back-patch of patch of 2009-01-08. This is
necessary in 8.3, as reported by Bjorn Munch. It's not currently
necessary in 8.2, AFAICS, but seems best to include it there too.

- In pgsql/src/backend/utils/adt/arrayfuncs.c, fix unnest() to handle
a toasted input array safely. Per report from Alvaro Herrera.

Heikki Linnakangas committed:

- Check that connection limit is within valid range. IOW, not < -1.
It's missing in older versions too, but it doesn't seem worth
back-porting. All negative are just harmlessly treated as "no
limit", and tightening the check might even brake an application
that relies on it.
