+<h2>Applied Patches</h2>
+<p>
+Michael Meskes committed:
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/preproc/README.parser, added some
+ explanation about how the parser is generated, taken from an email
+ by Zoltan Boszormenyi.
+</p>
+
+<p>
+- In ECPG, applied patch by Zoltan Boszormenyi to fix memory leak in
+ decimal handling.
+</p>
+
+<p>
+Andrew Dunstan committed:
+</p>
+
+<p>
+- In pgsql/src/pl/plperl/plperl.c, convert a perl array to a postgres
+ array when returned by Set Returning Functions as well as +non SRFs.
+ Backpatch to 8.1 where these facilities were introduced. with a
+ little help from Abhijit Menon-Sen.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Fix equivclass.c's not-quite-right strategy for handling X=X
+ clauses. The original coding correctly noted that these aren't just
+ redundancies (they're effectively X IS NOT NULL, assuming = is
+ strict). However, they got treated that way if X happened to be in
+ a single-member EquivalenceClass already, which could happen if
+ there was an ORDER BY X clause, for instance. The simplest and most
+ reliable solution seems to be to not try to process such clauses
+ through the EquivalenceClass machinery; just throw them back for
+ traditional processing. The amount of work that'd be needed to be
+ smarter than that seems out of proportion to the benefit. Per bug
+ #5084 from Bernt Marius Johnsen, and analysis by Andrew Gierth.
+</p>
+
+<p>
+- Allow MOVE FORWARD n, MOVE BACKWARD n, MOVE FORWARD ALL, MOVE
+ BACKWARD ALL in plpgsql. Clean up a couple of corner cases in the
+ MOVE/FETCH syntax. Pavel Stehule.
+</p>
+
+<p>
+- Assorted improvements in contrib/hstore. Remove the 64K limit on
+ the lengths of keys and values within an hstore. (This changes the
+ on-disk format, but the old format can still be read.) Add support
+ for btree/hash opclasses for hstore --- this is not so much for
+ actual indexing purposes as to allow use of GROUP BY, DISTINCT, etc.
+ Add various other new functions and operators. Andrew (RhodiumToad)
+ Gierth.
+</p>
+
+<p>
+- In pgsql/contrib/hstore/hstore_op.c, fix bogus Assert, per buildfarm
+ results.
+</p>
+
+<p>
+- Support "samehost" and "samenet" specifications in pg_hba.conf, by
+ enumerating the machine's IP interfaces to look for a match. Stef
+ Walter.
+</p>
+
+<p>
+- Fix erroneous handling of shared dependencies (ie dependencies on
+ roles) in CREATE OR REPLACE FUNCTION. The original code would
+ update pg_shdepend as if a new function was being created, even if
+ it wasn't, with two bad consequences: pg_shdepend might record the
+ wrong owner for the function, and any dependencies for roles
+ mentioned in the function's ACL would be lost. The fix is very
+ easy: just don't touch pg_shdepend at all when doing a function
+ replacement. Also update the CREATE FUNCTION reference page, which
+ never explained exactly what changes and doesn't change in a
+ function replacement. In passing, fix the CREATE VIEW reference
+ page similarly; there's no code bug there, but the docs didn't say
+ what happens.
+</p>
+
+<p>
+- Make sure that GIN fast-insert and regular code paths enforce the
+ same tuple size limit. Improve the error message for
+ index-tuple-too-large so that it includes the actual size, the
+ limit, and the index name. Sync with the btree occurrences of the
+ same error. Back-patch to 8.4 because it appears that the
+ out-of-sync problem is occurring in the field. Teodor Sigaev and
+ Tom Lane.
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster/pgstat.c, fix an oversight in an
+ 8.3-era patch: pgstat_initstats should allow stats to be collected
+ for sequences. Report and fix by Akira Kurosawa.
+</p>
+
+<p>
+- Fix a couple of issues in recent patch to print updates to
+ postgresql.conf settings: avoid calling superuser() in contexts
+ where it's not defined, don't leak the transient copies of
+ GetConfigOption output, and avoid the whole exercise in postmaster
+ child processes. I found that actually no current caller of
+ GetConfigOption has any use for its internal check of
+ GUC_SUPERUSER_ONLY. But rather than just remove that entirely, it
+ seemed better to add a parameter indicating whether to enforce the
+ check. Per report from Simon and subsequent testing.
+</p>
+
+<p>
+- In pgsql/src/backend/libpq/hba.c, fix assorted memory leaks in
+ pg_hba.conf parsing. Over a sufficiently large number of SIGHUP
+ cycles, these would have run the postmaster out of memory. Noted
+ while testing memory-leak scenario in postgresql.conf
+ configuration-change-printing patch.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/stylesheet.dsl, add tooltips to the header
+ links, and make title a link to the home page based on an idea by
+ Richard Huxton.
+</p>
+
+<p>
+Alvaro Herrera committed:
+</p>
+
+<p>
+- Ensure that a cursor has an immutable snapshot throughout its
+ lifespan. The old coding was using a regular snapshot, referenced
+ elsewhere, that was subject to having its command counter updated.
+ Fix by creating a private copy of the snapshot exclusively for the
+ cursor. Backpatch to 8.4, which is when the bug was introduced
+ during the snapshot management rewrite.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/config.sgml, document the purpose of the GUC
+ listen_addresses.
