Update PostgreSQL to latest versions.
The PostgreSQL Project today released
updates to all active branches of the
PostgreSQL object-relational database
system, including versions 8.3.6,
8.2.12, 8.1.16, 8.0.20 and 7.4.24. These
updates include two serious fixes, for
autovacuum crashes in version 8.1 and
GiST indexing data loss in 8.3, and
those two versions should be updated as
soon as possible.
These update releases also include
patches for several low-risk security
holes, as well as up to 17 other minor
fixes, depending on your major version
of PostgreSQL. Included as well are
Daylight Savings Time changes for Nepal,
Switzerland and Cuba. See the release
notes for full details.
The first serious issue affects users
who are using version 8.1 with
Autovacuum, which will fail when XID
rollover is required. The second serious
issue can cause data loss when CLUSTER
is used with GiST indexes (such as full
text indexes) on version 8.3. Both
issues are fixed in these releases.
