In order to address several issues identified since our last Point Releases, we have just released the following new versions of PostgreSQL: 7.3.11, 7.4.9 and 8.0.4.
A few of the more prominent fixes across all three versions are:
Fix error that allowed "VACUUM" to remove ctid chains too soon
Fix missing rows in queries like UPDATE a=... WHERE a... with GiST index on column a
Improve checking for partially-written WAL pages
Various memory leakage fixes
For a complete list of fixes in each release, please see the HISTORY file.
These Point Releases do not require a dump/reload from the previous Point, but *may* require one if upgrading from an earlier version. Please see the Release Notes to confirm procedures for upgrading if your current version is older then 1 Point Release.
