== Angewandte Patches ==

Magnus Hagander committed:

- In pgsql/src/backend/libpq/hba.c, disallow gssapi authentication on
  local connections, since it requires a hostname to function.  Noted
  by Zdenek Kotala.

- In pgsql/src/interfaces/libpq/fe-auth.c, require hostname to be set
  when using GSSAPI authentication. Without it, the GSSAPI libraries
  crash.  Noted by Zdenek Kotala.

- In pgsql/doc/src/sgml/ref/psql-ref.sgml, add missing space in
  example.  Tim Landscheidt.

Michael Meskes committed:

- In pgsql/src/interfaces/ecpg/ecpglib/error.c, better test the
  content of the SQLSTATE string in ecpglib than the pointer.

- In pgsql/src/interfaces/ecpg/ecpglib/error.c, backport fix from HEAD
  that makes ecpglib give the right SQLSTATE if the connection

- Ecpg now adds a unique counter to its varchar struct definitions to
  make these definitions unique, too.  It used to use the linenumber
  but in the rare case of two definitions in one line this was not

Bruce Momjian committed:

- In pgsql/src/bin/psql/command.c, return proper exit code (3) from
  psql when ON_ERROR_STOP=on and --single-transaction are both used
  and the failure happens in commit, e.g. failed deferred trigger.
  Also properly free BEGIN/COMMIT result structures from
  --single-transaction.  Per report from Dominic Bevacqua

- In pgsql/doc/src/sgml/config.sgml, remove unnecessary comma in

- In pgsql/doc/src/sgml/config.sgml, re-add comma, oops.

- In pgsql/src/timezone/zic.c, small adjustment by pgindent.

- In pgsql/src/backend/tsearch/wparser_def.c, allow underscores in
  tsearch email addressses, per RFC 5322 and report by Dan O'Hara.
  Patch by Teodor Sigaev

- In pgsql/doc/src/sgml/textsearch.sgml, document what user name email
  symbols are supported by tsearch.

- Add libpq warning message if the .pgpass-retrieved password fails.
  Add ERRCODE_INVALID_PASSWORD sqlstate error code.

- In pgsql/src/backend/libpq/pqcomm.c, move TCP keepalive macro
  definition.  Jaime Casanova

- In pgsql/src/backend/libpq/pqcomm.c, move more tcp keepalive macros
  to be consistent.

- In pgsql/src/backend/libpq/pqcomm.c, revert all keepalive moves,

Andrew Dunstan committed:

- In pgsql/src/pl/plperl/plperl.c, add checks for valid encoding of
  query strings passed to SPI by plperl.

Alvaro Herrera committed:

- Update time zone data files to tzdata release 2010e: DST law changes
  in Fiji, Samoa, Chile; corrections to recent changes in Paraguay and

- Improve PL/Perl documentation of database access functions.
  (Backpatch to 8.4 of a patch previously applied by Bruce Momjian to
  CVS HEAD) Alexey Klyukin.

Tom Lane committed:

- In pgsql/src/pl/plperl/plperl.c, use SvROK(sv) rather than directly
  checking SvTYPE(sv) == SVt_RV in plperl.  The latter is considered
  unwarranted chumminess with the implementation, and can lead to
  crashes with recent Perl versions.  Report and fix by Tim Bunce.
  Back-patch to all versions containing the questionable coding

- Preliminary release notes for releases 8.4.3, 8.3.10, 8.2.16,
  8.1.20, 8.0.24, 7.4.28.

- In pgsql/src/include/catalog/pg_constraint.h, update comment for
  pg_constraint.conindid to mention that it's used for exclusion
  constraints.  Not sure how we managed to update the comment for it
  in catalogs.sgml but miss this one.

- Simplify a couple of pg_dump and psql \d queries about index
  constraints by joining to pg_constraint.conindid, instead of the
  former technique of joining indirectly through pg_depend.  This is
  much more straightforward and probably faster as well.  I had
  originally desisted from changing these queries when conindid was
  added because I was worried about losing performance, but if we join
  on conrelid as well as conindid then the index on conrelid can be
  used when pg_constraint is large.

- In pgsql/src/bin/psql/describe.c, modify psql's \d printout to fold
  exclusion constraints in with regular indexes, rather than printing
  them twice.  Per my gripe when the exclusion constraint feature was

- In pgsql/src/backend/access/common/reloptions.c, add missing reset
  of need_initialization in reloptions code.  This resulted in useless
  extra work during every call of parseRelOptions, but no bad effects
  other than that.  Noted by Alvaro Herrera.

- In pgsql/src/timezone/pgtz.c, fix a commented-out block of code that
  pgindent didn't understand properly; it's been making that comment
  uglier with each run.

- In pgsql/src/backend/postmaster/pgstat.c, add some logging code for
  unexpected cases, particularly being unable to read a stats file for
  reasons other than ENOENT, and having to reset last_statrequest
  because it's later than current time in the collector.  Not clear if
  this will shed any light on the "pgstat wait timeout" business, but
  it seems like a good idea in general.  In passing, do some
  message-style-police work on recently-added
  pgstat_reset_shared_counters code.

- Update oidjoins regression test for 9.0.

ITAGAKI Takahiro committed:

- pg_start_backup() can use a share lock to lock ControlFileLock
  instead of an exclusive lock.  The change is almost for code
  cleanup.  Since there seems to be no performance benefits from it,
  backports should not be needed.  Fujii Masao

Robert Haas committed:

- In pgsql/src/backend/commands/tablecmds.c, fix incorrect comment
  about permissions checking being done in utility.c.  Noted while
  reviewing a patch from KaiGai Kohei.

Heikki Linnakangas committed:

- In pgsql/src/backend/storage/ipc/standby.c, fix comment which was
  apparently copy-pasted from another function.

- In pgsql/src/backend/storage/ipc/procarray.c, fix bug in
  KnownAssignedXidsMany(). I saw this when looking at the assertion
  failure reported by Erik Rijkers, but this alone doesn't explain the

Marc Fournier committed:

- Tag 8.4.3, 8.3.10, 8.2.16, 8.1.20, 8.0.24, and 7.4.28.

Peter Eisentraut committed:

- In pgsql/doc/src/sgml/runtime.sgml, update shared memory
  configuration information for Linux In particular, the assertion
  that shmall is sufficiently sized by default is slowly becoming

- In pgsql/doc/src/sgml/plpython.sgml, add some more structure and
  bits of information to PL/Python documentation
