+<h2>Applied Patches</h2>
+<p>
+Teodor Sigaev committed:
+</p>
+
+<p>
+- Fix usage of char2wchar/wchar2char. Changes: pg_wchar and wchar_t
+ could have different size, so char2wchar doesn't call
+ pg_mb2wchar_with_len to prevent out-of-bound memory bug. Make
+ char2wchar/wchar2char symmetric, now they should not be called with
+ C-locale because mbstowcs/wcstombs oftenly doesn't work correct with
+ C-locale. Text parser uses pg_mb2wchar_with_len directly in case of
+ C-locale and multibyte encoding Per bug report by Hiroshi Inoue and
+ following discussion. Backpatch up to 8.2 when multi-byte support
+ was implemented in tsearch.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- When we are in error recursion trouble, arrange to suppress
+ translation and encoding conversion of any elog/ereport message
+ being sent to the frontend. This generalizes a patch that I put in
+ last October, which suppressed translation of only specific messages
+ known to be associated with recursive can't-translate-the-message
+ behavior. As shown in bug #4680, we need a more general answer in
+ order to have some hope of coping with broken encoding conversion
+ setups. This approach seems a good deal less klugy anyway. Patch
+ in all supported branches.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/error/elog.c, ooops ... fix some
+ confusion between gettext() and _() in my previous patch. This has
+ moved around in past releases, so just copying-and-pasting from HEAD
+ didn't work as intended.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/adt/float.c, put back our old workaround
+ for machines that declare cbrt() in math.h but fail to provide the
+ function itself. Not sure how we escaped testing anything later
+ than 7.3 on such cases, but they still exist, as per Andr?
+ Volpato's report about AIX 5.3.
+</p>
+
+<p>
+- Fix column privilege checking for cases where parent and child have
+ different attribute numbering. Also, a parent whole-row reference
+ should not require select privilege on child columns that aren't
+ inherited from the parent. Problem diagnosed by KaiGai Kohei,
+ though this isn't exactly his patch.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/backup.sgml, remove documentation of
+ log_restartpoints setting, which is obsoleted in favor of
+ log_checkpoints. Fujii Masao
+</p>
+
+<p>
+- Teach the planner to support index access methods that only
+ implement amgettuple or only implement amgetbitmap, instead of the
+ former assumption that every AM supports both APIs. Extracted with
+ minor editorialization from Teodor Sigaev's fast-GIN-insert patch;
+ whatever becomes of that, this seems like a simple and reasonable
+ generalization of the index AM interface spec.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- In pgsql/src/include/storage/lwlock.h, remove the placeholder
+ LWLockId in place of the removed FreeSpaceLock. As pointed out by
+ ITAGAKI Takahiro, we split SInvalLock into two in 8.4, so to keep
+ the numbers of the rest of the locks unchanged from 8.3, we don't
+ need a placeholder.
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster/postmaster.c, fix copy-pasto in the
+ patch to allow background writer to run during recovery: if
+ background writer or pgstat process dies during recovery (or any
+ other child process, but those two are the only ones running), send
+ SIGQUIT to the startup process using correct pid.
+</p>
+
+<p>
+- In pgsql/src/backend/commands/functioncmds.c, add some sanity checks
+ to CREATE CAST ... WITHOUT FUNCTION. Disallow composite, enum and
+ array types, as those are surely not binary-compatible with anything
+ else because of the embedded OIDs. Inspired by bug report by Oleg
+ Serov.
+</p>
+
+<p>
+- Reload config file in startup process on SIGHUP. Fujii Masao.
+</p>
+
+<p>
+- Add MUST (Mauritius Island Summer Time) to the list of known
+ abbreviations. Mauritius began using DST in the summer 2008-2009;
+ the Olson library has been updated already. Xavier Bugaud
+</p>
+
+<p>
+Magnus Hagander committed:
+</p>
+
+<p>
+- In pgsql/src/backend/libpq/hba.c, log a warning instead of shutting
+ down the system if we can't load pg_hba.conf on reload (for example
+ due to a permission error). Selena Deckelmann.
+</p>
+
+<p>
+- In pgsql/src/backend/libpq/hba.c, change hba load failure message to
+ LOG instead of WARNING. Per comment from Tom Lane.
+</p>
+
+<p>
+- In pgsql/src/backend/libpq/hba.c, make pg_hba parsing report all
+ errors in the file before aborting the load, instead of just
+ reporting the first one. Selena Deckelmann
+</p>
+
+<p>
+- In pgsql/src/tools/msvc/Mkvcbuild.pm, fix MSVC build for new ways to
+ pull in keywords.c and kwlookup.c.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/src/backend/storage/file/fd.c, don't actively violate the
+ system limit of maximum open files (RLIMIT_NOFILE). This avoids
+ irritating kernel logs (if system overstep violations are enabled)
+ and also the grsecurity alert when starting PostgreSQL. Original
+ patch by Jacek Drobiecki.
+</p>
+
+<p>
+- Add new SQL:2008 error codes for invalid LIMIT and OFFSET values.
+ Remove unused nonstandard error code that was perhaps intended for
+ this but never used.
+</p>
+
+<p>
+- Provide some proper minimal documentation for the pg_dump(all)
+ --binary-upgrade option. We don't want to commit to what it does,
+ but hiding it will only cause confusion.
+</p>
+
+<p>
+- In pgsql/src/backend/parser/scan.l, clarify to the translator that
+ yyerror() deals with the translation of "syntax error", not the
+ literal string. I was previously confused on this matter, but I
+ have now verified that everything is translated properly.
+</p>
+
+<p>
+- In pgsql/src/bin/pg_dump/pg_backup_archiver.c, message tuning.
+</p>
+
+<p>
+Alvaro Herrera committed:
+</p>
+
+<p>
+- Separate the key word list that lived in keywords.c into a new
+ header file kwlist.h, to avoid having to link the backend object
+ file into other programs like pg_dump. We can now simply symlink a
+ single source file from the backend (kwlookup.c, containing the
+ shared routine ScanKeywordLookup) and compile it locally, which is a
+ lot cleaner.
+</p>
+
+<p>
+- In pgsql/src/bin/scripts/Makefile, avoid MSVC breakage caused by my
+ previous commit by not using a variable in the src/bin/scripts
+ Makefile.
+</p>
+
+<p>
+- On Windows, call bind_textdomain_codeset on domains other than the
+ default one, too, so that the codeset is properly mapped on the
+ newly added PL domains.
+</p>
+
+<p>
+- Add comments about kwlookup.c expectations.
+</p>
+
+<p>
+- pg_bind_textdomain_codeset must exist only on ENABLE_NLS.
+</p>
+
+<p>
+- Revert pg_bind_textdomain_codeset to a existant-but-empty function
+ when ENABLE_NLS is not defined, for better compatibility of the
+ backend with modules compiled the other way. Per note from Tom Lane
+ after my previous commit.
+</p>
