+<h2>PostgreSQL 9.0 Feature of the Week</h2>
+<p>
+You can create per-column triggers, i.e. triggers which only fire on
+modification of specified columns. The syntax, as described in
+SQL:2008, is CREATE TRIGGER trigger_name (BEFORE|AFTER) UPDATE OF col1
+[,col2...coln] ON tablename FOR EACH ROW EXECUTE PROCEDURE
+trigger_function();

+<h2>Applied Patches</h2>
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- Add cross-reference from wal_level to hot_standby setting. Update
+ the PITR documentation to mention that you need to set wal_level to
+ 'archive' or 'hot_standby', to enable WAL archiving. Per Simon
+ Riggs's request.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/high-availability.sgml, change "literal" tag
+ to the more appropriate "firstterm", when describing what
+ "eventually consistent" means.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/config.sgml, change wording so that you don't
+ need to understand that wal_levels form a hierarchy. Per Simon
+ Riggs's suggestion.
+</p>
+
+<p>
+- In pgsql/src/backend/access/transam/xlog.c, need to hold
+ ControlFileLock while updating control file. Update
+ minRecoveryPoint in control file when replaying a parameter change
+ record, to ensure that we don't allow hot standby on WAL generated
+ without wal_level='hot_standby' after a standby restart.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/intarray.sgml, fix incorrect parameter tag in
+ docs, spotted by KOIZUMI Satoru.
+</p>
+
+<p>
+Alvaro Herrera committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/mvcc.sgml, remove spurious dot, per bug #5446
+ reported by Koizumi Satoru.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Fix backpatching error in recent patch for ALTER USER f RESET ALL
+ behavior. The argument list for array_set() changed in 8.2 (in
+ connection with allowing nulls in arrays) but the newer argument
+ list was used in the patches applied to 8.1 and 8.0 branches. The
+ patch for 7.4 was OK though. Per compiler warnings.
+</p>
+
+<p>
+- In pgsql/src/bin/psql/psqlscan.l, fix psql to not go into infinite
+ recursion when expanding a variable that refers to itself (directly
+ or indirectly). Instead, print a message when recursion is
+ detected, and don't expand the repeated reference. Per bug #5448
+ from Francis Markham. Back-patch to 8.0. Although the issue exists
+ in 7.4 as well, it seems impractical to fix there because of the
+ lack of any state stack that could be used to track active
+ expansions.
+</p>
+
+<p>
+- In pgsql/src/makefiles/Makefile.linux, on Linux, use
+ --enable-new-dtags when specifying -rpath to linker. This should
+ allow LD_LIBRARY_PATH to work as desired. Per trouble report from
+ Andy Colson.
+</p>
+
+<p>
+- Work around a subtle portability problem in use of printf %s format.
+ Depending on which spec you read, field widths and precisions in %s
+ may be counted either in bytes or characters. Our code was assuming
+ bytes, which is wrong at least for glibc's implementation, and in
+ any case libc might have a different idea of the prevailing encoding
+ than we do. Hence, for portable results we must avoid using
+ anything more complex than just "%s" unless the string to be printed
+ is known to be all-ASCII. This patch fixes the cases I could find,
+ including the psql formatting failure reported by Hernan Gonzalez.
+ In HEAD only, I also added comments to some places where it appears
+ safe to continue using "%.*s".
+</p>
+
+<p>
+- Adjust comments about avoiding use of printf's %.*s. My initial
+ impression that glibc was measuring the precision in characters
+ (which is what the Linux man page says it does) was incorrect. It
+ does take the precision to be in bytes, but it also tries to
+ truncate the string at a character boundary. The bottom line
+ remains the same: it will mess up if the string is not in the
+ encoding it expects, so we need to avoid %.*s anytime there's a
+ significant risk of that. Previous code changes are still good, but
+ adjust the comments to reflect this knowledge. Per research by
+ Hernan Gonzalez.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/ecpg.sgml, fix typo: PGTYPES_NUM_OVERFLOW
+ should be PGTYPES_NUM_UNDERFLOW. Noted by KOIZUMI Satoru.
+</p>
+
+<p>
+- In pgsql/src/backend/replication/walsender.c, fix missing static
+ declaration for XLogRead().
+</p>
+
+<p>
+- In pgsql/src/bin/psql/print.c, suppress signed-vs-unsigned-char
+ warning.
+</p>
+
+<p>
+ITAGAKI Takahiro committed:
+</p>
+
+<p>
+- In pgsql/src/port/chklocale.c, code page for EUC-KR is surely 51949.
+</p>
+
+<p>
+Michael Meskes committed:
+</p>
+
+<p>
+- In pgsql/src/interfaces/ecpg/ecpglib/connect.c, ECPG connect routine
+ only checked for NULL to find empty parameters, but user and
+ password can also be "".
+</p>

+WAL receipt timestamp instead of log timestamp, per suggestion from
+Tom Lane.
+</p>
+
+<p>
+Pavel Stehule sent in a patch to add new optional arguments to
+string_to_array() and array_to_string() which allow for an explicit
+NULL string rather than to have NULL disappear unconditionally.
