v7.2.1 Released: Critical Bug Fix

Over this past weekend, the PostgreSQL Global Development Group packaged
up and put onto our ftp server PostgreSQL v7.2.1 ... a bug fix release, it
fixes a critical bug in v7.2:

sequence counters will go backwards after a crash

Other fixes since v7.2 include:

Fix pgaccess kanji-coversion key binding (Tatsuo)
Optimizer improvements (Tom)
cash I/O improvements (Tom)
New Russian FAQ
Compile fix for missing AuthBlockSig (Heiko)
Additional time zones and time zone fixes (Thomas)
Allow psql \connect to handle mixed case database and user names (Tom)
Return proper OID on command completion even with ON INSERT rules (Tom)
Allow COPY FROM to use 8-bit DELIMITERS (Tatsuo)
Fix bug in extract/date_part for milliseconds/microseconds (Tatsuo)
Improve handling of multiple UNIONs with different lengths (Tom)
contrib/btree_gist improvements (Teodor Sigaev)
contrib/tsearch dictionary improvements, see README.tsearch for
an additional installation step (Thomas T. Thai, Teodor Sigaev)
Fix for array subscripts handling (Tom)
Allow EXECUTE of "CREATE TABLE AS ... SELECT" in PL/PgSQL (Tom)

Upgrading to v7.2.1 from v7.2 *does not* require a dump/reload, but it is
required from all previous releases ...

Due to the nature of the bug with the sequence counters, it is *highly*
recommended that anyone running v7.2 upgrade to the latest version at
their earliest convience ...
