== PostgreSQL in the News ==

Planet PostgreSQL: http://planet.postgresql.org/

PostgreSQL Weekly News is brought to you this week by David Fetter and
Josh Berkus.

Submit news and announcements by Sunday at 3:00pm Pacific time.
Please send English language ones to david@fetter.org, German language
to pwn@pgug.de, Italian language to pwn@itpug.org.

== Applied 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.
