+<h2>Applied Patches</h2>
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/src/pl/tcl/expected/pltcl_queries_1.out, add expected file
+ for locale-enabled installations.
+</p>
+
+<p>
+- In pgsql/src/bin/psql/help.c, fix my typo.
+</p>
+
+<p>
+- In pgsql/src/bin/psql/command.c, no period if it's not a sentence.
+</p>
+
+<p>
+- Polish SQL/MED terminology
+</p>
+
+<p>
+- In pgsql/src/bin/psql/help.c, in the \? output, align the columns
+ consistently.
+</p>
+
+<p>
+- In pgsql/src/bin/psql/help.c, update line count for \? output

+</p>
+
+<p>
+- In pgsql/src/backend/catalog/catalog.c, complete list of valid fork

+
+<p>

+ single quotes.
+</p>
+
+<p>
+- Gettext plural support. In the backend, I changed only a handful of
+ exemplary or important-looking instances to make use of the plural
+ support; there is probably more work there. For the rest of the
+ source, this should cover all relevant cases.
+</p>
+
+<p>

+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, Fix release note attribution:
+ "Support the IS0 8601 time interval syntax (Tom, Kevin Grittner)"
+ per Ron Mayer.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, first round of release note

+ Greg Stark.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, document in release notes that

+ that dtrace probes evaluate their parameters even when not active.
+ Explain how to prevent that with an ENABLED() check.

+- Better document PQinitSSL(0) behavior in regards to libcrypto.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/alter_role.sgml, better document that SET
+ ROLE does not uset ALTER ROLE SET settings; suggested wording from
+ Josh Berkus.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, update release notes to say
+ citext is multi-byte aware, per suggestion from patch author.
+</p>
+
+<p>
+- In pgsql/src/interfaces/libpq/fe-secure.c, clarify variable naming:
+ pq_initssllib -> pq_init_ssl_lib.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, consistent 8.4 release note
+ naming for Itagaki Takahiro.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, add SGML markup for
+ commands/literal/application/etc in release notes; still more work
+ to do.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, more release note markup.

+ 8.3.7.
+</p>

+ because parameter is now 3-valued, not just enable/disable.
+</p>

+ notes; markup/cleanup/reorganization still required.

+ current as of 2009-03-16.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, adjust AS OF release notes
+ markup.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Const-ify the parse table passed to fillRelOptions. The previous
+ coding meant it had to be built on-the-fly at each entry to
+ default_reloptions.
+</p>
+
+<p>
+- Implement "fastupdate" support for GIN indexes, in which we try to
+ accumulate multiple index entries in a holding area before adding
+ them to the main index structure. This helps because bulk insert is
+ (usually) significantly faster than retail insert for GIN. This
+ patch also removes GIN support for amgettuple-style index scans.
+ The API defined for amgettuple is difficult to support with
+ fastupdate, and the previously committed partial-match feature
+ didn't really work with it either. We might eventually figure a way
+ to put back amgettuple support, but it won't happen for 8.4.
+ catversion bumped because of change in GIN's pg_am entry, and
+ because the format of GIN indexes changed on-disk (there's a
+ metapage now, and possibly a pending list). Teodor Sigaev.
+</p>
+
+<p>
+- In pgsql/src/backend/optimizer/plan/planner.c, fix stupid
+ parenthesization mistake. Per bug #4728 from Bruce Toll.
+</p>
+
+<p>
+- Install a search tree depth limit in GIN bulk-insert operations, to
+ prevent them from degrading badly when the input is sorted or nearly
+ so. In this scenario the tree is unbalanced to the point of
+ becoming a mere linked list, so insertions become O(N^2). The
+ easiest and most safely back-patchable solution is to stop growing
+ the tree sooner, ie limit the growth of N. We might later consider
+ a rebalancing tree algorithm, but it's not clear that the benefit
+ would be worth the cost and complexity. Per report from Sergey
+ Burladyan and an earlier complaint from Heikki Linnakangas.
+ Back-patch to 8.2; older versions didn't have GIN indexes.
+</p>
+
+<p>
+- In pgsql/contrib/pgcrypto/pgp.h, fix old thinko in pgp.h: the idea
+ is to declare some named enum types, not global variables of
+ anonymous enum types. This didn't actually hurt much because most
+ linkers will just merge the duplicated definitions ... but some
+ will complain. Per bug #4731 from Ceriel Jacobs. Backpatch to 8.1
+ --- the declarations don't exist before that.
+</p>
+
+<p>
+- Adjust the APIs for GIN opclass support functions to allow the
+ extractQuery() method to pass extra data to the consistent() and
+ comparePartial() methods. This is the core infrastructure needed to
+ support the soon-to-appear contrib/btree_gin module. The APIs are
+ still upward compatible with the definitions used in 8.3 and before,
+ although *not* with the previous 8.4devel function definitions.
+ catversion bump for changes in pg_proc entries (although these are
+ just cosmetic, since GIN doesn't actually look at the function
+ signature before calling it...). Teodor Sigaev and Oleg Bartunov
+</p>
+
+<p>
+- Add btree_gin contrib module. Teodor Sigaev and Oleg Bartunov.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, fix markup so that 'make
+ HISTORY' works. A couple very minor editorial improvements.
+</p>
+
+<p>
+- If we expect a hash join to be performed in multiple batches,
+ suppress "physical tlist" optimization on the outer relation (ie,
+ force a projection step to occur in its scan). This avoids storing
+ useless column values when the outer relation's tuples are written
+ to temporary batch files. Modified version of a patch by Michael
+ Henderson and Ramon Lawrence.
+</p>
+
+<p>
+- In pgsql/src/backend/commands/copy.c, adjust phrasing of complaints
+ about multi-byte COPY delimiter strings. Per pgsql-hackers
+ discussion of 2009-02-17.
+</p>
+
+<p>
+- Fix a couple of places that still claimed LC_COLLATE and LC_CTYPE
+ can't be changed after initdb.
+</p>
+
+<p>
+- In pgsql/contrib/pg_standby/pg_standby.c, Make pg_standby's
+ maxretries option do what one would expect. Fujii Masao.
+</p>
+
+<p>
+- In pgsql/src/backend/catalog/index.c, teach reindex_index() to clear
+ pg_index.indcheckxmin when possible. Greg Stark, slightly modified
+ by me.
+</p>
+
+<p>
+- Fix possible failures when a tuplestore switches from in-memory to
+ on-disk mode while callers hold pointers to in-memory tuples. I
+ reported this for the case of nodeWindowAgg's primary scan tuple,
+ but inspection of the code shows that all of the calls in
+ nodeWindowAgg and nodeCtescan are at risk. For the moment, fix it
+ with a rather brute-force approach of copying whenever one of the
+ at-risk callers requests a tuple. Later we might think of some sort
+ of reference-count approach to reduce tuple copying.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/adt/xml.c, add an errdetail explaining
+ why we reject infinite dates and timestamps while converting to XML.
+ Bernd Helmle
+</p>
+
+<p>
+- On Solaris, we should only force use of our own getopt(); it's okay
+ to use the system's getopt_long(). The previous coding was the
+ result of a sloppy discussion that failed to draw this distinction.
+ The result was that PG programs don't handle options as users of
+ that platform expect. Per gripe from Chuck McDevitt. Although this
+ is a pre-existing bug, I'm not backpatching since I think we could
+ do with a bit of beta testing before concluding this is really OK.
+</p>
+
+<p>
+Andrew Dunstan committed:
+</p>
+
+<p>
+- Remove munging of xml and xpath params to xpath(). The XML must now
+ be a well formed XML document.
+</p>
+
+<p>
+Magnus Hagander committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, fix release notes about pg_hba
+ changes.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, clarify new SSL certificate
+ verification in libpq.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, fix markup, per Devrim GUNDUZ.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- In pgsql/src/bin/psql/tab-complete.c, fix tab completion of ANALYZE
+ VERBOSE <tab>. It was previously confused with EXPLAIN ANALYZE
+ VERBOSE. Greg Sabino Mullane, reformatted by myself. Backpatch to
+ 8.1, where the bug was introduced.
+</p>
+
+<h2>Rejected Patches (for now)</h2>
+<p>
+Srinath K's patch to implement a global index on partitioned tables,
+as it came with an IP disclaimer which precluded anyone's looking at
+it.
+</p>
+
+<p>
+Hitoshi Harada's patches to fix a tuplestore API issue where a
+ScanTupleSlot is not always valid as long as the tuplestore-handling
+code expects it to be. Tom Lane used forced copying instead.
+</p>

+</p>
+
+<p>
+Andrew (RhodiumToad) Gierth sent in a patch to change hstore so that
+keys and values can be of arbitrary length, so long as the hstore
+itself fits in varlena, supports btree and hash opclasses for hstores,
+which in turn allow for UNIQUE constraints, and aggregation, adds
+binary I/O, a flock of operators which relate hstores to text, text[]
+and record, adds GiST and GIN support, converts between hstore and
+record, and populates a record from an hstore.

+value.
+</p>
+
+<p>
+Taro Minowa sent in a patch for 8.5 which allows pg_dump to dump
