+== PostgreSQL 8.4 Feature of the Week ==
+</p>
+
+<p>
+Function Editing: psql will allow you to edit functions in-place with
+\ef using your favorite command-line editor.
+</p>
+
+<h2>PostgreSQL Tip of the Week</h2>
+<p>
+bonnie++, dd, and iozone are all good tools to do a quick test of your
+filesystem's I/O performance. If your database is larger than RAM, it
+can't go any faster than the storage subsystem can!

+<h2>Applied Patches</h2>
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/src/bin/pg_dump/pg_dump.c, add -w option to --help output.
+ It was apparently forgotten when -w was implemented.
+</p>
+
+<p>
+- Rename pg_restore -m to -j, and add documentation about what good
+ numbers are. Per discussion on -hackers.
+</p>
+
+<p>
+Bruce Momjian committed:
+</p>
+
+<p>
+- In pgsql/src/backend/utils/adt/datetime.c, document that datetime
+ year '0' is considered in a recent century, not just '00'.
+</p>
+
+<p>
+- In pgsql/src/backend/utils/adt/datetime.c, improve zero-year
+ comments.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/client-auth.sgml, clarify 'cert'
+ authentication documention.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/libpq.sgml, clarify libpq 'sslverify'
+ documentation wording.
+</p>
+
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/release.sgml, add just-assigned CVE number to
+ release notes for recent security issue.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/intarray.sgml, be more clear about when to use
+ gist__int_ops vs. gist__intbig_ops. Per suggestion from Ron Mayer.
+</p>
+
+<p>
+- Optimize multi-batch hash joins when the outer relation has a
+ nonuniform distribution, by creating a special fast path for the
+ (first few) most common values of the outer relation. Tuples having
+ hashvalues matching the MCVs are effectively forced to be in the
+ first batch, so that we never write them out to the batch temp
+ files. Bryce Cutt and Ramon Lawrence, with some editorialization by
+ me.
+</p>
+
+<p>
+- Remove the datetime keywords ABSTIME and RELTIME, which we'd been
+ treating as noise words for the last twelve years, for compatibility
+ with Berkeley-era output formatting of the special INVALID values
+ for those datatypes. Considering that the datatypes themselves have
+ been deprecated for awhile, this is taking backwards compatibility a
+ little far. Per gripe from Josh Berkus.
+</p>
+
+<p>
+- Remove the -d and -D options of pg_dump and pg_dumpall. The
+ functionality is still available, but you must now write the long
+ equivalent --inserts or --column-inserts. This change is made to
+ eliminate confusion with the use of -d to specify a database name in
+ most other Postgres client programs. Original patch by Greg Sabino
+ Mullane, modified per subsequent discussion.
+</p>
+
+<p>
+- Clean up pg_SSPI_error() coding a little bit: make the messages more
+ consistent, translate where intended, const-ify declarations.
+ Resolves a gripe from Alvaro Herrera as well as some stuff I didn't
+ like.
+</p>
+
+<p>
+- Add isExtend to the parameters of the buffer_read_start and
+ buffer_read_done DTrace probes, so that ordinary reads can be
+ distinguished from relation extension operations. Move
+ buffer_read_start probe to before the smgrnblocks() call that's
+ needed in the isExtend case, since really that step should be
+ charged as part of the time needed for the extension operation.
+ (This makes it slightly harder to match the read_start with the
+ associated read_done, since now you can't match them on blockNumber,
+ but it should still be possible since isExtend operations on the
+ same relation can never be interleaved.) Per recent discussion. In
+ passing, add the page identity (forkNum/blockNum) to the parameters
+ of the buffer_flush_start/buffer_flush_done probes, which were
+ unaccountably lacking the info.
+</p>
+
+<p>
+- More fixes for 8.4 DTrace probes. Remove useless
+ BUFFER_HIT/BUFFER_MISS probes --- the BUFFER_READ_DONE probe
+ provides the same information and more besides. Expand the
+ LOCK_WAIT_START/DONE probe arguments so that there's actually some
+ chance of telling what is being waited for. Update and clean up the
+ documentation.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- In pgsql/src/backend/postmaster, fix Windows-specific race condition
+ in syslogger. This could've been the cause of the "could not write
+ to log file: Bad file descriptor" errors reported at
+ <a href="http://archives.postgresql.org//pgsql-general/2008-06/msg00193.php">http://archives.postgresql.org//pgsql-general/2008-06/msg00193.php</a>
+ Backpatch to 8.3, the race condition was introduced by the CSV
+ logging patch. Analysis and patch by Gurjeet Singh.
+</p>
+
+<p>
+- Add seven kanji characters defined in the Windows 950 codepage to
+ our big5/win950 <-> UTF8 conversion tables. Per report by Roger
+ Chang.
+</p>
+
+<p>
+- Fix case of the just resurrected UCS_to_BIG5.pl script, and update
+ Makefile to use it.
+</p>
+
+<p>
+- In pgsql/contrib/pg_standby/pg_standby.c, don't intercept SIGQUIT as
+ a signal to trigger failover; that's what postmaster uses for
+ immediate shutdown. Trap SIGUSR1 as the preferred signal for that.
+ Per report by Fujii Masao and subsequent discussion on -hackers.
+</p>
+
+<p>
+- In pgsql/contrib/pg_standby/pg_standby.c, don't set the signal
+ handler for SIGQUIT on Windows. Buildfarm shows that reinstalling
+ the default signal handler doesn't work as it is on Windows.
+ Presumably core dumps on SIGQUIT are not a problem on Windows, so
+ rather than figure out what header files or other changes are
+ required to make it work, just don't bother.
+</p>
