+<h2>Applied Patches</h2>
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- Fix an old bug in multixact and two-phase commit. Prepared
+ transactions can be part of multixacts, so allocate a slot for each
+ prepared transaction in the "oldest member" array in multixact.c. On
+ PREPARE TRANSACTION, transfer the oldest member value from the
+ current backends slot to the prepared xact slot. Also save and
+ recover the value from the 2PC state file. The symptom of the bug
+ was that after a transaction prepared, a shared lock still held by
+ the prepared transaction was sometimes ignored by other
+ transactions. Fix back to 8.1, where both 2PC and multixact were
+ introduced.
+</p>
+
+<p>
+Magnus Hagander committed:
+</p>
+
+<p>
+- In pgsql/src/interfaces/libpq/win32.mak, add missing library to
+ standalone libpq build on Win32. Hiroshi Saito.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Use diff's -w switch only on Windows, to avoid problems with
+ inconsistent newline representations. Per buildfarm results and
+ subsequent discussion. Sync up a couple of other places that had
+ their own policies.
+</p>
+
+<p>
+- Simplify psql's new linestyle behavior to default to linestyle=ascii
+ all the time, rather than hoping we can tell whether the terminal
+ supports UTF8 characters. Per discussion.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release-8.5.sgml, fix missing end tag, per
+ Jeff Davis.
+</p>
+
+<p>
+- Eliminate a lot of list-management overhead within
+ join_search_one_level by adding a requirement that build_join_rel
+ add new join RelOptInfos to the appropriate list immediately at
+ creation. Per report from Robert Haas, the list_concat_unique_ptr()
+ calls that this change eliminates were taking the lion's share of
+ the runtime in larger join problems. This doesn't do anything to
+ fix the fundamental combinatorial explosion in large join problems,
+ but it should push out the threshold of pain a bit further. Note:
+ because this changes the order in which joinrel lists are built, it
+ might result in changes in selected plans in cases where different
+ alternatives have exactly the same costs. There is one example in
+ the regression tests.
+</p>
+
+<p>
+- Add support for an application_name parameter, which is displayed in
+ pg_stat_activity and recorded in log entries. Dave Page, reviewed
+ by Andres Freund.
+</p>
+
+<p>
+- Add support for anonymous code blocks (DO blocks) to PL/Perl. Patch
+ by Joshua Tolley, reviews by Brendan Jurd and Tim Bunce.
+</p>
+
+<p>
+- Make pg_stat_activity.application_name visible to all users, rather
+ than being hidden when current_query is. Relocate it to a column
+ position more consistent with that behavior. Per discussion.
+</p>
+
+<p>
+- Add some opr_sanity checks that the lengths of the various
+ argument-info arrays in a pg_proc entry match. Seems like an easy
+ mistake to make when manually adjusting these values in a pg_proc.h
+ entry.
+</p>
+
+<p>
+- In pgsql/src/pl/plperl/plperl.c, fix session-lifespan memory leak
+ when a plperl function is redefined: we have to tell Perl it can
+ release its compiled copy of the function text. Noted by Alexey
+ Klyukin. Back-patch to 8.2 --- the problem exists further back, but
+ this patch won't work without modification, and it's probably not
+ worth the trouble.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- Add PG_MODULE_MAGIC and some missing include files to examples.
+ Euler Taveira de Oliveira.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/func.sgml, fix syntax in extract() examples.
+ Erik Rijkers.
+</p>
+
+<p>
+- In pgsql/src/interfaces/libpq/fe-connect.c, remove prefix "ERROR:"
+ from some messages, to make everything consistent
+</p>
+
+<p>
+- In pgsql/src/interfaces/libpq/fe-connect.c, error when a specified
+ connection service is not found, instead of ignoring it.
+</p>
+
+<p>
+Michael Meskes committed:
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/ecpglib/misc.c, made function better
+ readable.
+</p>
+
+<p>
+- Added dynamic cursor names to ecpg. Almost the whole patch was done
+ by Boszormenyi Zoltan, with only a minor tweak or two from me.
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/preproc/ecpg.addons, synced addon rules
+ after some renamings.
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/ChangeLog, forgot to add dynamic
+ cursors to Changelog.
+</p>
+
+<p>
+- In ECPG, added missing files.
+</p>
+
+<p>
+- In ECPG, added script to check if all rule re-definition in
+ ecpg.addons are indeed used in the build process. If not the build
+ process will stop with an error message.
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/ecpglib/data.c, if no result is given
+ NOTFOUND should be returned. Check for empty result string too.
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/preproc/ecpg.addons, remove */
+ characters from declare cursor statements before putting them into a
+ comment.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/vacuumdb.sgml, document ath vacuumdb
+ --analyze does analyze _also_, not in place of vacuum.
+</p>
+
+<p>
+- Improve test descriptions displayed during test_fsync; increase
+ default loops to 5k.
+</p>
+
+<p>
+- Add link to external fsync testing script and our fsync test tool.
+</p>
