+<h2>Reviews</h2>
+<h2>Applied Patches</h2>
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Make an editorial pass over the 9.0 release notes. This is mostly
+ about grammar, style, and presentation, though I did find a few
+ small factual errors.
+</p>
+
+<p>
+- In pgsql/contrib/pg_archivecleanup/pg_archivecleanup.c, make
+ pg_archivecleanup log messages more consistent. Erik Rijkers
+</p>
+
+<p>
+- Marginal code cleanup for streaming replication. There is no reason
+ that proc.c should have to get involved in this dirty hack for
+ letting the postmaster know which children are walsenders. Revert
+ that file to the way it was, and confine the kluge to pmsignal.c and
+ postmaster.c.
+</p>
+
+<p>
+- In pgsql/src/backend/commands/explain.c, make EXPLAIN show the
+ function call expression of a FunctionScan plan node, but only in
+ VERBOSE mode. Per discussion.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, further editing of release
+ notes.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, update 9.0 release notes for
+ changes since beta4. Note: as usual, bug fixes that were also
+ applied in back branches are not considered material to include in a
+ new major release's notes.
+</p>
+
+<p>
+- In pgsql/src/bin/psql/command.c, avoid passing signed chars to
+ <ctype.h> functions ... same old portability mistake as always. Per
+ buildfarm member pika.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/unaccent.sgml, docs review for unaccent: fix
+ grammar, markup, etc.
+</p>
+
+<p>
+- In pgsql/src/backend/port/sysv_shmem.c, improve hint message for
+ ENOMEM failure from shmget(). It turns out that some platforms
+ return ENOMEM for a request that violates SHMALL, whereas we were
+ assuming that ENOSPC would always be used for that. Apparently the
+ latter is a Linuxism while ENOMEM is the BSD tradition. Extend the
+ ENOMEM hint to suggest that raising SHMALL might be needed. Per
+ gripe from A.M. Backpatch to 9.0, but not further, because this
+ doesn't seem important enough to warrant creating extra translation
+ work in the stable branches. (If it were, we'd have figured this
+ out years ago.)
+</p>
+
+<p>
+- In a bit more., document filtering dictionaries in textsearch.sgml.
+ While at it, copy-edit the description of prefix-match marker
+ support in synonym dictionaries, and clarify the description of the
+ default
+</p>
+
+<p>
+- In pgsql/config/prep_buildtree, don't auto-create the subdirectories
+ holding built documentation in a VPATH build tree. If we actually
+ build the docs in the VPATH tree, those dirs will get created then;
+ but if they're present and empty, they capture the vpathsearch
+ searches in "make install", preventing installation of prebuilt docs
+ that might exist in the source tree. Per bug #5595 from Dmtiriy
+ Igrishin. Fix based on idea from Peter Eisentraut.
+</p>
+
+<p>
+- In pgsql/src/backend/executor/execQual.c, fix
+ ExecMakeTableFunctionResult to verify that all rows returned by a
+ SRF returning "record" actually do have the same rowtype. This is
+ needed because the parser can't realistically enforce that they will
+ all have the same typmod, as seen in a recent example from David
+ Wheeler. Back-patch to 8.0, which is as far back as we have the
+ notion of RECORD subtypes being distinguished by typmod. Wheeler's
+ example depends on 8.4-and-up features, but I suspect there may be
+ ways to provoke similar failures before 8.4.
+</p>
+
+<p>
+- Update time zone data files to tzdata release 2010l: DST law changes
+ in Egypt and Palestine. Added new names for two Micronesian
+ timezones: Pacific/Chuuk is now preferred over Pacific/Truk (and the
+ preferred abbreviation is CHUT not TRUT) and Pacific/Pohnpei is
+ preferred over Pacific/Ponape. Historical corrections for Finland.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ddl.sgml, explain automatic creation (or lack
+ of it) of indexes for the various types of constraints. Kevin
+ Grittner.
+</p>
+
+<p>
+- Document the existence of the socket lock file under
+ unix_socket_directory, which is perhaps not a terribly good spot for
+ it but there doesn't seem to be a better place. Also add a
+ source-code comment pointing out a couple reasons for having a
+ separate lock file. Per suggestion from Greg Smith.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/libpq.sgml, remove obsolete remark that
+ PQprepare() is more flexible than PREPARE. Spotted by Dmitriy
+ Igrishin. Back-patch to 8.2, which is when the PREPARE statement
+ was improved to allow parameter types to be omitted.
+</p>
+
+<p>
+- Reduce PANIC to ERROR in some occasionally-reported btree failure
+ cases. This patch changes _bt_split() and _bt_pagedel() to throw a
+ plain ERROR, rather than PANIC, for several cases that are reported
+ from the field from time to time: 1. right sibling's left-link
+ doesn't match; 2. PageAddItem failure during _bt_split(); 3. parent
+ page's next child isn't right sibling during _bt_pagedel(). In
+ addition the error messages for these cases have been made a bit
+ more verbose, with additional values included. The original
+ motivation for PANIC here was to capture core dumps for subsequent
+ analysis. But with so many users whose platforms don't capture core
+ dumps by default, or who are unprepared to analyze them anyway, it's
+ hard to justify a forced database restart when we can fairly easily
+ detect the problems before we've reached the critical sections where
+ PANIC would be necessary. It is not currently known whether the
+ reports of these messages indicate well-hidden bugs in Postgres, or
+ are a result of storage-level malfeasance; the latter possibility
+ suggests that we ought to try to be more robust even if there is a
+ bug here that's ultimately found. Backpatch to 8.2. The code
+ before that is sufficiently different that it doesn't seem worth the
+ trouble to back-port further.
+</p>
+
+<p>
+ITAGAKI Takahiro committed:
+</p>
+
+<p>
+- Add string functions: concat(), concat_ws(), left(), right(), and
+ reverse(). Pavel Stehule, reviewed by me.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/config.sgml, update autovacuum_freeze_max_age
+ documentation to mention that the default is low because of pg_clog
+ file removal. Backpatch to 9.0.X.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, clarifications for 9.0
+ release notes Josh Berkus
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/high-availability.sgml, fix awkward wording in
+ Incrementally Updated Backups docs. Backpatch to 9.0.X.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, update release notes, per
+ comments from Simon Riggs.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/high-availability.sgml, remove docs for
+ "Incrementally Updated Backups" because it was of questionable
+ reliability; information moved to a wiki:
+ <a href="http://wiki.postgresql.org/wiki/Incrementally_Updated_Backups">http://wiki.postgresql.org/wiki/Incrementally_Updated_Backups</a>
+ Backpatch to 9.0.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/src/Makefile.global.in, when in automatic dependency mode,
+ never delete any intermediate files automatically. Otherwise, the
+ following could happen: When starting from a clean source tree, the
+ first build would delete the intermediate file, but also create the
+ dependency file, which mentions the intermediate file, thus making
+ it non-intermediate. The second build will then need to rebuild the
+ now non-intermediate missing file. So the second build will do work
+ even though nothing had changed. One place where this happens is
+ the .c -> .o -> .so chain for some contrib modules.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/catalogs.sgml, add missing description of
+ reloftype field.
+</p>
+
+<p>
+- In pgsql/src/pl/plpython/plpython.c, catch null pointer returns from
+ PyCObject_AsVoidPtr and PyCObject_FromVoidPtr. This is reproducibly
+ possible in Python 2.7 if the user turned PendingDeprecationWarning
+ into an error, but it's theoretically also possible in earlier
+ versions in case of exceptional conditions. Backpatched to 8.0.
+</p>
+
+<p>
+- Translation updates for 9.0rc1.
+</p>
+
+<p>
+- Small refactoring of makeVar() from a TargetEntry.
+</p>
+
+<p>
+Alvaro Herrera committed:
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlog.c, remove duplicate
+ translatable phrase.
+</p>
+
+<p>
+- Improve wording for privilege description on certain failure
+ messages; the original misleadingly suggests that only access is
+ meant, causing confusion. Per recent trouble report by Robert
+ McGehee on pgsql-admin.
+</p>
+
+<p>
+Marc Fournier committed:
+</p>
+
+<p>
+- tag rc1 ... final stretch ...
+</p>
+
+<p>
+Robert Haas committed:
+</p>
+
+<p>
+- Rewrite comment code for better modularity, and add necessary
+ locking. Review by Alvaro Herrera, KaiGai Kohei, and Tom Lane.
+</p>
+
+<p>
+- In pgsql/src/backend/catalog/objectaddress.c, insert additional
+ compiler placation into objectaddress.c. Peter Eisentraut reports
+ that some bits of the "address" variable in get_object_address()
+ give "may be used uninitialized" warnings; this likes the only
+ excuse his compiler could have for thinking that's possible.
