+<h2>Applied Patches</h2>
+<p>
+Michael Meskes committed:
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/test/preproc/strings.pgc, fixed ECPG
+ regression test to make sure it uses absolute paths for include
+ files instead of relative ones which break vpath builds.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Fix an oversight in join-removal optimization: we have to check not
+ only for plain Vars that are generated in the inner rel and used
+ above the join, but also for PlaceHolderVars. Per report from Oleg
+ Kolyhalin.
+</p>
+
+<p>
+- In pgsql/src/test/regress/output/constraints.source, fix regression
+ test breakage from recent change in default name of
+ exclusion-constraint index.
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster/pgstat.c, now that we know
+ last_statrequest > last_statwrite can be observed in the buildfarm,
+ expend a little more effort on the log message for it.
+</p>
+
+<p>
+- In pgsql/src/backend/libpq/hba.c, fix thinko in log message for
+ "sameuser" ident map mismatch: the provided and authenticated
+ usernames were swapped. Reported by Bryan Henderson in bug #5386.
+ Also clean up poorly-maintained header comment for this function.
+</p>
+
+<p>
+- In pgsql/contrib/intarray/_int_gin.c, fix ginint4_queryextract() to
+ actually do what it was intended to do for an unsatisfiable query,
+ such as indexcol && empty_array. It should return -1 to tell GIN no
+ scan is required; but silly typo disabled the logic for that,
+ resulting in unnecessary "GIN indexes do not support whole-index
+ scans" error. Per bug report from Jeff Trout. Back-patch to 8.3
+ where the logic was introduced.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- Re-order createuser and vacuumedb documentation options, for
+ consistency. Gabrielle Roth.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, properly credit Simon Riggs
+ for functions pg_last_xlog_replay_location, etc.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, add back other xlog()
+ function author names.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, typo fix from Erik
+ (breinbaas) Rijkers.
+</p>
+
+<p>
+- Document in postgresql.conf that the max_standby_delay default is 30
+ 'seconds'.
+</p>
+
+<p>
+Simon Riggs committed:
+</p>
+
+<p>
+- In pgsql/src/backend/commands/indexcmds.c, shorten suffix of
+ automatically created indexes to "_excl" when using exclusion
+ constraints, in line with string length of other pre-9.0 suffixes.
+</p>
+
+<p>
+- In pgsql/src/backend/replication/walsender.c, reduce CPU utilisation
+ of WALSender process. Process was using 10% CPU doing nothing,
+ caused by naptime specified in milliseconds yet units of pg_usleep()
+ parameter is microseconds. Correctly specifying units reduces call
+ frequency by 1000. Reduction in CPU consumption verified.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/init/postinit.c, change replication
+ connection log format to allow for a database called replication.
+ Add host and port details, following format of messages in
+ BackendInitialize().
+</p>
+
+<p>
+- In pgsql/src/backend/replication/walsender.c, additional thoughts on
+ WALSender cpu reduction. Use long type and alter a comment to
+ reduce confusion.
+</p>
+
+<p>
+- Modify some new and pre-existing messages for translatability.
+</p>
+
+<p>
+- Derive latestRemovedXid for btree deletes by reading heap pages.
+ The WAL record for btree delete contains a list of tids, even when
+ backup blocks are present. We follow the tids to their heap tuples,
+ taking care to follow LP_REDIRECT tuples. We ignore LP_DEAD tuples
+ on the understanding that they will always have xmin/xmax earlier
+ than any LP_NORMAL tuples referred to by killed index tuples. Iff
+ all tuples are LP_DEAD we return InvalidTransactionId. The heap
+ relfilenode is added to the WAL record, requiring API changes to
+ pass down the heap Relation. XLOG_PAGE_MAGIC updated.
+</p>
+
+<p>
+ITAGAKI Takahiro committed:
+</p>
+
+<p>
+- Each worker thread will have its own log file in pgbench to avoid
+ interleaved writes. The first worker still uses "pgbench_log.<pid>"
+ for the name, but additional workers use
+ "pgbench_log.<pid>.<serial-number>" instead. Reported by Greg
+ Smith.
+</p>
+
+<p>
+- Remove CRs for each line in pgbench.sgml.
+</p>
+
+<p>
+- Clean up logging codes and add documentation. Add English
+ documentation. Split warm-standby and internal module
+ documentation. Change the default for
+ pg_statsinfo.syslog_line_prefix to 't %p '. Support non-default
+ log_error_verbosity. Support local, GMT and UTC for log_timezone,
+ but we cannot support others because postgres uses own timezone
+ implemntation. Simplify codes for log_line_prefix.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/preproc/ecpg.addons, remove useless
+ double assignment GCC 4.5 complained about it.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- In pgsql/src/backend/replication/README, update description of
+ walrcv_receive() function to match reality.
+</p>
+
+<p>
+- In pgsql/src/backend/replication/walsender.c, flush CopyOutResponse
+ when starting streaming in walsender, so that it's not delayed until
+ the first WAL record is sent. Fujii Masao.
+</p>
+
+<p>
+Andrew Dunstan committed:
+</p>
+
+<p>
+- In pgsql/src/Makefile.global.in, mark "installcheck-parallel",
+ "world", "install-world" and "installcheck-world" make targets as
+ PHONY. Fujii Masao.
+</p>
+
+<p>
+Alvaro Herrera committed:
+</p>
+
+<p>
+- Prevent ALTER USER f RESET ALL from removing the settings that were
+ put there by a superuser -- "ALTER USER f RESET setting" already
+ disallows removing such a setting. Apply the same treatment to
+ ALTER DATABASE d RESET ALL when run by a database owner that's not
+ superuser.
+</p>
+

+Hitoshi Harada.
