+<h2>Applied Patches</h2>
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlog.c, if a corrupt WAL record
+  is received by streaming replication, disconnect and retry.  If the
+  record is genuinely corrupt in the master database, there's little
+  hope of recovering, but it's better than simply retrying to apply
+  the corrupt WAL record in a tight loop without even trying to
+  retransmit it, which is what we used to do.
+</p>
+
+<p>
+ITAGAKI Takahiro committed:
+</p>
+
+<p>
+- In pgsql/src/bin/psql/po/ja.po, fix typo in Japanese translation for
+  psql "Use \d+ to list them."
+</p>
+
+<p>
+- Add new GUC categories corresponding to sections in docs, and move
+  description for vacuum_defer_cleanup_age to the correct category.
+  Sections in postgresql.conf are also sorted in the same order with
+  docs.  Per gripe by Fujii Masao, suggestion by Heikki Linnakangas,
+  and patch by me.
+</p>
+
+<p>
+- In pgsql/src/include/replication/walsender.h, remove prototype of
+  GetOldestWALSendPointer(), that is marked as NOT_USED.
+</p>
+
+<p>
+Simon Riggs committed:
+</p>
+
+<p>
+- In pgsql/contrib/Makefile, new contrib module for use as an
+  archive_cleanup_command, or as a standalone utility for removing
+  files from archive.
+</p>
+
+<p>
+- Files for pg_archivecleanup.
+</p>
+
+<p>
+- Docs for pg_archivecleanup.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/plperl.sgml, fix doc plperl doc with is -> are
+  change.
+</p>
+
+<p>
+- Properly define pg_upgrade global variable, per bug report from
+  Chris Ruprecht on Mac (64 bit).
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/select.sgml, clarify SELECT FOR UPDATE
+  behavior in docs.
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/option.c, fix storage of getopt()
+  return, should be 'int', for pg_upgrade.  Steve Singer.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, 9.0 release notes updates.
+  Josh Berkus
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, update doc description for
+  9.0 release note item: Have <command>SELECT</> and <command>CREATE
+  TABLE AS</> return row counts to the client
+</p>
+
+<p>
+- In pgsql/contrib/pg_upgrade/tablespace.c, fix pg_upgrade to remove
+  malloc(0) call.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- In pgsql/contrib/dblink/dblink.c, rearrange dblink's
+  dblink_build_sql_insert() and related routines to open and lock the
+  target relation just once per SQL function call.  The original
+  coding obtained and released lock several times per call.  Aside
+  from saving a not-insignificant number of cycles, this eliminates
+  possible race conditions if someone tries to modify the relation's
+  schema concurrently.  Also centralize locking and
+  permission-checking logic.  Problem noted while investigating a
+  trouble report from Robert Voinea --- his problem is still to be
+  fixed, though.
+</p>
+
+<p>
+- Consolidate and improve checking of key-column-attnum arguments for
+  dblink_build_sql_insert() and related functions.  In particular, be
+  sure to reject references to dropped and out-of-range column
+  numbers.  The numbers are still interpreted as physical column
+  numbers, though, for backward compatibility.  This patch replaces
+  Joe Conway's patch of 2010-02-03, which handled only some aspects of
+  the problem.
+</p>
+
+<p>
+- Fix dblink_build_sql_insert() and related functions to handle
+  dropped columns correctly.  In passing, get rid of some dead logic
+  in the underlying get_sql_insert() etc functions --- there is no
+  caller that will pass null value-arrays to them.  Per bug report
+  from Robert Voinea.
+</p>
+
+<p>
+- Change the interpretation of the primary_key_attnums parameter of
+  dblink_build_sql_insert() and related functions.  Now the column
+  numbers are treated as logical not physical column numbers.  This
+  will provide saner behavior in the presence of dropped columns;
+  furthermore, if we ever get around to allowing rearrangement of
+  logical column ordering, the original definition would become nearly
+  untenable from a usability standpoint.  Per recent discussion of
+  dblink's handling of dropped columns.  Not back-patched for fear of
+  breaking existing applications.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/libpq.sgml, fix typo, init => int, per KOIZUMI
+  Satoru.
+</p>
+
+<p>
+- Don't allow walsender to send WAL data until it's been safely
+  fsync'd on the master.  Otherwise a subsequent crash could cause the
+  master to lose WAL that has already been applied on the slave,
+  resulting in the slave being out of sync and soon corrupt.  Per
+  recent discussion and an example from Robert Haas.  Fujii Masao.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/copy.sgml, add missing close brackets in
+  old-style COPY syntax diagram.  Spotted by Evan Carroll.
+</p>
+
+<p>
+- In pgsql/contrib/pg_archivecleanup/pg_archivecleanup.c, clean up
+  pg_archivecleanup's error and logging output: put newlines in sane
+  places, make messages follow project's message style guidelines.
+  Also, avoid closedir(NULL).  Fujii Masao and Tom Lane
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlog.c, make
+  RemoveOldXlogFiles's debug printout match style used elsewhere: log
+  and seg aren't an XLogRecPtr and shouldn't be printed like one.
+  Fujii Masao.
+</p>
+
+<p>
+- Clean up some randomness associated with trace_recovery_messages:
+  don't put the variable declaration in the middle of a bunch of
+  externs, and do use extern where it should be used.
+</p>
+
+<p>
+- Fix mishandling of whole-row Vars referencing a view or sub-select.
+  If such a Var appeared within a nested sub-select, we failed to
+  translate it correctly during pullup of the view, because the
+  recursive call to replace_rte_variables_mutator was looking for the
+  wrong sublevels_up value.  Bug was introduced during the addition of
+  the PlaceHolderVar mechanism.  Per bug #5514 from Marcos Castedo.
+</p>
+
+<p>
+Andrew Dunstan committed:
+</p>
+
+<p>
+- In pgsql/src/tools/msvc/Mkvcbuild.pm, unbreak MSVC builds for
+  pg_archivecleanup by linking with libpgport.
+</p>
+
+<p>
+- Remove perl symbol table additions for plperl functions, and mention
+  of it in the release notes, as it is not apparently providing
+  anything useful.
+</p>
+
+<p>
+Robert Haas committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/analyze.sgml, document new 9.0 behavior of
+  ANALYZE on inheritance hierarchies.  In particular, note that
+  autovacuum does not yet understand that it might need to vacuum
+  inheritance parents as a result of changes to the child tables.
+</p>
+
+<p>
+- Remove hstore's text[] => text[] operator.  This is not yet in any
+  released version, so we still have the option to backtrack.
+  Instead, document hstore(text[], text[]).  Per discussion.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/func.sgml, document that receive location can
+  rewind if replication restarts.  Fujii Masao, with some further
+  wordsmithing by me.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- Refactor sprintf calls with computed format strings into multiple
+  calls with constant format strings, so that the compiler can more
+  easily check the formats for correctness.
+</p>
+
+<p>
+- Add notes that CREATE/DROP CONVERSION is similar to CREATE/DROP
+  TRANSLATION in the SQL standard.
+</p>
