+<h2>Applied Patches</h2>
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- In pgsql/src/backend/storage/ipc/procsignal.c, fix typo in comment.
+</p>
+
+<p>
+Simon Riggs committed:
+</p>
+
+<p>
+- In pgsql/src/backend/storage/ipc/procarray.c, teach GetOldestXmin()
+ about KnownAssignedXids during recovery. Very minor issue, though
+ this is required for a later patch. Reported by Heikki Linnakangas.
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlog.c, truncate subtrans after
+ each restartpoint. Issue reported by Harald Kolb, patch by Fujii
+ Masao, review by me.
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlog.c, fix misleading DEBUG2
+ issued during RemoveOldXlogFiles().
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlogutils.c, fix oversight in
+ RelFileNodeBackend patch: CreateFakeRelcacheEntry needs to
+ initialize the rd_backend field of a fake Relation entry correctly.
+ Fortunately, that is easy, since only non-temp relations should ever
+ be mentioned in the WAL stream.
+</p>
+
+<p>
+- In pgsql/src/backend/storage/ipc/procarray.c, cosmetic fixes for
+ KnownAssignedXidsGetOldestXmin, per Fujii Masao.
+</p>
+
+<p>
+- In pgsql/src/include/port/solaris.h, back-port into 8.2 an old fix
+ to ensure that BYTE_ORDER gets set correctly on 64-bit Intel
+ Solaris. Per my proposal yesterday, 8.2 is where we will start
+ considering this platform supported. While this patch itself could
+ easily go into older branches, there's not a huge amount of point
+ unless we also make some significantly-more-invasive changes in the
+ spinlock support.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-9.0.sgml, improve release notes'
+ description of Teodor Sigaev's fixes for polygon overlaps and
+ contains operators.
+</p>
+
+<p>
+- Clarify documentation of handling of null arguments for aggregates.
+ Per discussion.
+</p>
+
+<p>
+- Fix up flushing of composite-type typcache entries to be driven
+ directly by SI invalidation events, rather than indirectly through
+ the relcache. In the previous coding, we had to flush a
+ composite-type typcache entry whenever we discarded the
+ corresponding relcache entry. This caused problems at least when
+ testing with RELCACHE_FORCE_RELEASE, as shown in recent report from
+ Jeff Davis, and might result in real-world problems given the kind
+ of unexpected relcache flush that that test mechanism is intended to
+ model. The new coding decouples relcache and typcache management,
+ which is a good thing anyway from a structural perspective. The
+ cost is that we have to search the typcache linearly to find entries
+ that need to be flushed. There are a couple of ways we could avoid
+ that, but at the moment it's not clear it's worth any extra trouble,
+ because the typcache contains very few entries in typical operation.
+ Back-patch to 8.2, the same as some other recent fixes in this
+ general area. The patch could be carried back to 8.0 with some
+ additional work, but given that it's only hypothetical whether we're
+ fixing any problem observable in the field, it doesn't seem worth
+ the work now.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ecpg.sgml, clean up some bad grammar and
+ punctuation in description of ecpg's decimal type. Per KOIZUMI
+ Satoru.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ecpg.sgml, clean up description of ecpg's
+ dtcvfmtasc function. Per KOIZUMI Satoru.
+</p>
+
+<p>
+- 9.1alpha1 release notes.
+</p>
+
+<p>
+- In HEAD only, revert kluge solution for preventing misuse of
+ pg_get_expr(). A data-type-based solution, which is much cleaner
+ and more bulletproof, will follow shortly. It seemed best to make
+ this a separate commit though.
+</p>
+
+<p>
+- Install a data-type-based solution for protecting pg_get_expr().
+ Since the code underlying pg_get_expr() is not secure against
+ malformed input, and can't practically be made so, we need to
+ prevent miscreants from feeding arbitrary data to it. We can do
+ this securely by declaring pg_get_expr() to take a new datatype
+ "pg_node_tree" and declaring the system catalog columns that hold
+ nodeToString output to be of that type. There is no way at SQL
+ level to create a non-null value of type pg_node_tree. Since the
+ backend-internal operations that fill those catalog columns operate
+ below the SQL level, they are oblivious to the datatype relabeling
+ and don't need any changes.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/misc/ps_status.c, pad the ps_status
+ display with nulls, not blanks, on Darwin. A long time ago, this
+ didn't work nicely, but it seems to work on all recent versions of
+ OS X. The blank-pad method is less desirable since it results in
+ lots of extra space in ps' output. Per Alexey Klyukin.
+</p>
+
+<p>
+- In pgsql/src/backend/catalog/pg_constraint.c, GROUP BY can only
+ infer functional dependency from non-deferrable primary keys.
+ Peter's original patch had this right, but I dropped the check while
+ revising the code to search pg_constraint instead of pg_index.
+ Spotted by Dean Rasheed.
+</p>
+
+<p>
+Alvaro Herrera committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/create_aggregate.sgml, add missing markup
+ for translatability.
+</p>
+
+<p>
+Robert Haas committed:
+</p>
+
+<p>
+- In pgsql/src/backend/catalog/objectaddress.c, fix typo. Pointed out
+ by Kevin Grittner.
