PostgreSQL 8.3.4, 8.2.10, etc. Update Release

Updates for all maintained versions of PostgreSQL are available today: 
8.3.4, 8.2.10, 8.1.14, 8.0.18 and 7.4.22.  These releases fix more than 
thirty minor issues reported and patched over the last three months.  As 
some of these issues carry a risk of data loss, administrators of 
production applications should upgrade in their next possible scheduled 
downtime.

Additionally, this minor release also contains updates for the following 
timezones to support changes in local laws: Argentina, Bahamas, Brazil, 
Mauritius, Morocco, Pakistan, Palestine, and Paraguay.  Users in these 
timezones should plan to upgrade as soon as possible to avoid improper 
calculation of daylight savings time.

Issues fixed include autovacuum crashes reported by several users, two 
Heap Only Tuple bugs, a foreign key failure condition, a too-small lock 
address space, two Write Ahead Log bugs, several planner mistakes, and 
numerous "corner condition" bugs.  See the release notes for more details.

As with other minor releases, users are not required to dump and reload 
their database in order to apply this update release; you may simply 
shut down PostgreSQL and update its binaries.  Users skipping more than 
one update may need to check the release notes for extra, post-update 
steps.  As previously announced, only versions 8.2.10 and 8.3.4 of the 
Windows binaries are being released, as we no longer support 8.0 and 8.1 
on Windows.
