== Applied Patches ==

Heikki Linnakangas committed:

- In pgsql/src/pl/plpgsql/src/pl_exec.c, in a PL/pgSQL "FOR cursor"
  statement, the statements executed in the loop might close the
  cursor, rendering the Portal pointer to it invalid.  Closing the
  cursor in the middle of the loop is not a very sensible thing to do,
  but we must handle it gracefully and throw an error instead of

Robert Haas committed:

- Minor markup improvements for Hot Standby documentation.

- Deprecate the use of => as an operator name.  In HEAD, emit a
  warning when an operator named => is defined.  In both HEAD and the
  backbranches (except in 8.2, where contrib modules do not have
  documentation), document that hstore's text => text operator may be
  removed in a future release, and encourage the use of the
  hstore(text, text) function instead.  This function only exists in
  HEAD (previously, it was called tconvert), so backpatch it back to
  8.2, when hstore was added.  Per discussion.

- In pgsql/contrib/hstore/expected/hstore.out, updated expected-output
  file for hstore.  This is an oversight in my previous patch to
  deprecate => as an operator name.  Per buildfarm.

- Add TCP keepalive support to libpq.  This adds four additional
  connection parameters to libpq: keepalives, keepalives_idle,
  keepalives_count, and keepalives_interval.  keepalives default to
  on, per discussion, but can be turned off by specifying
  keepalives=0.  The remaining parameters, where supported, can be
  used to adjust how often keepalives are sent and how many can be
  lost before the connection is broken.  The immediate motivation for
  this patch is to make sure that walreceiver will eventually notice
  if the master reboots without closing the connection cleanly, but it
  should be helpful in other cases as well.  Tollef Fog Heen, Fujii
  Masao, and me.

- In pgsql/src/backend/postmaster/postmaster.c, add stray "else" that
  seems to have gone missing.

- In pgsql/doc/src/sgml/release-9.0.sgml, further 9.0 release notes
  updates.  Josh Berkus.

- In pgsql/doc/src/sgml/high-availability.sgml, some copy-editing of
  the Hot Standby documentation.  Thanks to Joshua Tolley for the

- In pgsql/doc/src/sgml/installation.sgml, make AIX suggestions about
  disabling ipv6 more version-sensitive.  Chris Browne, based on a
  report from John Pierce.

- In pgsql/doc/src/sgml/libpq.sgml, rewrite docs for new libpq
  keepalive parameters.  The revised documentation makes it more clear
  that these are client-side parameters, rather than server side
  parameters.  It also puts the main point of each parameter first,
  and consolidates the conditions under which it might be ignored in a
  single list at the end.

Bruce Momjian committed:

- In pgsql/doc/src/sgml/ref/pg_ctl-ref.sgml, update pg_ctl docs to
  explain server output behavior differences on win32 and non-win32

- Fix pg_upgrade's use of pg_ctl on Win32 to not send command and
  sever output to the same file, because it is impossible.  Also set
  user name for pg_dumpall in pg_upgrade.

- Add username designations to all pg_upgrade utility calls that
  support it.

- In pgsql/doc/src/sgml/ref/alter_table.sgml, mention that when alter
  rewrites a table, indexes are also rebuilt.

Simon Riggs committed:

- Fix log_temp_files docs and comments to say bytes not kilobytes.
  stat(2) field st_size returns bytes not kilobytes.  Bug found during
  recent performance tuning for PostgreSQL user.

Tom Lane committed:

- Fix thinko in tok_is_keyword(): it was looking at the wrong union
  variant of YYSTYPE, and hence returning the wrong answer for cases
  where a plpgsql "unreserved keyword" really does conflict with a
  variable name.  Obviously I didn't test this enough :-(.  Per bug
  #5524 from Peter Gagarinov.

- In pgsql/src/bin/pg_dump/pg_backup_custom.c, fix pg_restore so
  parallel restore doesn't fail when the input file doesn't contain
  data offsets (which it won't, if pg_dump thought its output wasn't
  seekable).  To do that, remove an unnecessarily aggressive error
  check, and instead fail if we get to the end of the archive without
  finding the desired data item.  Also improve the error message to be
  more specific about the cause of the problem.  Per discussion of
  recent report from Igor Neyman.  Back-patch to 8.4 where parallel
  restore was introduced.
