+<h2>Applied Patches</h2>
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- 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
+ crashing.
+</p>
+
+<p>
+Robert Haas committed:
+</p>
+
+<p>
+- Minor markup improvements for Hot Standby documentation.
+</p>
+
+<p>
+- 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.
+</p>
+
+<p>
+- 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.
+</p>
+
+<p>
+- 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.
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster/postmaster.c, add stray "else" that
+ seems to have gone missing.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, further 9.0 release notes
+ updates. Josh Berkus.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/high-availability.sgml, some copy-editing of
+ the Hot Standby documentation. Thanks to Joshua Tolley for the
+ review.
+</p>
+
+<p>
+- 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.
+</p>
+
+<p>
+- 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.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- 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
+ platforms.
+</p>
+
+<p>
+- 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.
+</p>
+
+<p>
+- Add username designations to all pg_upgrade utility calls that
+ support it.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/alter_table.sgml, mention that when alter
+ rewrites a table, indexes are also rebuilt.
+</p>
+
+<p>
+Simon Riggs committed:
+</p>
+
+<p>
+- 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.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- 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.
+</p>
+
+<p>
+- 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.
+</p>
+
