+<h2>Applied Patches</h2>
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/src/interfaces/libpq/fe-secure.c, message wordsmithing
+</p>
+
+<p>
+- Alter the regression test cases that rely on the sort order of "ch"
+ between "cg" and "ci". This eliminates a test failure on the
+ following glibc locales: br_FR, cs_CZ, cy_GB, es_EC, es_US, hsb_DE,
+ ig_NG, ik_CA, sk_SK.
+</p>
+
+<p>
+- Alter regression test cases that rely on the sort order of "aa".
+ Some locales (da_DK, fo_FO, kl_GL, nb_NO, nn_NO in glibc) sort "aa"
+ after "z".
+</p>
+
+<p>
+- Avoid regression test cases that fail in locales that sort "v" and
+ "w" equally (in glibc: et_EE, sv_SE, tk_TM). It turns out that this
+ was already taken care of previously by select_1.out, which I had
+ forgotten to update for an unrelated change. But might as well
+ avoid the issue altogether.
+</p>
+
+<p>
+- Revise the permission checking on user mapping DDL commands.
+ CREATE/ALTER/DROP USER MAPPING are now allowed either by the
+ server owner or by a user with USAGE privileges for his own
+ user name. This is more or less what the SQL standard wants
+ anyway (plus "implementation-defined") Hide
+ information_schema.user_mapping_options.option_value, unless
+ the current user is the one associated with the user mapping,
+ or is the server owner and the mapping is for PUBLIC, or is a
+ superuser. This is to protect passwords. Also, fix a bug in
+ information_schema._pg_foreign_servers, which hid servers using
+ wrappers where the current user did not have privileges on the
+ wrapper. The correct behavior is to hide servers where the
+ current user has no privileges on the server.
+</p>
+
+<p>
+- In pgsql/src/nls-global.mk, do not msgmerge against /dev/null; merge
+ against the pot file itself instead.
+</p>
+
+<p>
+- Automatic view update rules. Bernd Helmle.
+</p>
+
+<p>
+- Recreate ecpg_config.h with a stamp file created by config.status,
+ same way pg_config.h is handled. This avoids reruns of
+ config.status on every build, if configure has been rerun.
+</p>
+
+<p>
+- Message style review for ecpg.
+</p>
+
+<p>
+Magnus Hagander committed:
+</p>
+
+<p>
+- Use the new text domain names ("postgres-8.4" instead of
+ "postgres"). Hiroshi Inoue.
+</p>
+
+<p>
+- In pgsql/src/tools/msvc/Install.pm, install .mo files for NLS as
+ <program>-<version>.mo when building with MSVC as well. Same change
+ as made earlier for autoconf builds. Per Hiroshi Inoue.
+</p>
+
+<p>
+- Make some strings translatable again that were accidentally removed
+ in earlier patch to fix "printf-arguments".
+</p>
+
+<p>
+- Make win32 builds always do SetEnvironmentVariable() when doing
+ putenv(). Also, if linked against other versions than the default
+ MSVCRT library (for example the MSVC build which links against
+ MSVCRT80), also update the cache in the default MSVCRT at the same
+ time. This should fix the issues with setting LC_MESSAGES on the
+ MSVC build. Original patch from Hiroshi Inoue and Hiroshi Saito,
+ much rewritten by me.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/adt/pg_locale.c, remove stray ' character
+ at end of line. For some reason it broke OpenBSD compile even when
+ it's inside a #ifdef WIN32 block.....
+</p>
+
+<p>
+- In pgsql/src/backend/utils/mb/mbutils.c, explicitly bind gettext to
+ the correct encoding on Windows. Original patch from Hiroshi Inoue.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- In pgsql/src/interfaces/libpq/fe-secure.c, fix accidental (I
+ suppose) introduction of non-ASCII quote marks.
+</p>
+
+<p>
+- Support column-level privileges, as required by SQL standard.
+ Stephen Frost, with help from KaiGai Kohei and others
+</p>
+
+<p>
+- In pgsql/src/backend/libpq/ip.c, tweak the existing special case for
+ AIX in pg_getaddrinfo_all() to handle yet another failure case in
+ AIX's getaddrinfo(). Per report and patch by Andrew Chernow.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- In pgsql/src/bin/psql/describe.c, document RELKIND_SPECIAL reference
+ in psql, from <= 8.1.X.
+</p>
+
+<p>
+- Make psql \d and \dt consistent for system tables, i.e prevent \d
+ from showing system tables, make \dS pattern show system table
+ details, and have \dtS show system and _user_ tables, to be
+ consistent with other \d* commands.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/psql-ref.sgml, update \d*S documentation
+ to be more accurate; system objects are added to the display, not
+ restricted in the display; new text: The letter <literal>S</literal>
+ adds the listing of system objects; without <literal>S</literal>,
+ only non-system objects are shown.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ref/select.sgml, document that SELECT FOR
+ UPDATE/SHARE with ORDER BY might return results in the incorrect
+ order, per bug 4593. Backpatch to 8.3.X.
+</p>
+
+<p>
+Alvaro Herrera committed:
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster/autovacuum.c, fix erroneous memory
+ context switch in autovacuum, which was returning to a context long
+ after it had been destroyed. Per problem report from Justin Pasher.
+ Patch by Tom Lane and me. 8.3 and later do not have this bug,
+ because this code has been restructured for unrelated reasons. In
+ 8.2 it does not manifest as a crash, but it still seems safer fixing
+ it nonetheless.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- Add a new option to RestoreBkpBlocks() to indicate if a cleanup lock
+ should be used instead of the normal exclusive lock, and make WAL
+ redo functions responsible for calling RestoreBkpBlocks(). They know
+ better what kind of a lock they need. At the moment, this just
+ moves things around with no functional change, but makes the hot
+ standby patch that's under review cleaner.
+</p>
+
+<p>
+- Add new SPI_OK_REWRITTEN return code to SPI_execute and friends, for
+ the case that the command is rewritten into another type of command.
+ The old behavior to return the command tag of the last executed
+ command was pretty surprising. In PL/pgSQL, for example, it meant
+ that if a command was rewritten to a utility statement, FOUND wasn't
+ set at all.
+</p>
+
+<p>
+- Forgot to handle the new SPI_OK_REWRITTEN result code in a couple
+ places.
+</p>
+
+<p>
+- Update comments to reflect that tgenabled is not a boolean anymore.
+ Jonah Harris, with minor tinkering by me.
+</p>
+
+<p>
+- In pgsql/src/backend/commands/vacuumlazy.c, only skip pages marked
+ as clean in the visibility map, if the last 32 pages were marked as
+ clean as well. The idea is to avoid defeating OS readahead by
+ skipping a page here and there, and also makes it less likely that
+ we miss an opportunity to advance relfrozenxid, for the sake of only
+ a few skipped pages.
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlog.c, put back fast-path for
+ the case that there's no backup blocks in RestoreBkpBlocks. Went
+ missing in my recent refactoring patch, as pointed out by Simon's
+ hot standby patch.
+</p>
