(RHSA-2004:489) rh-postgresql security update

PostgreSQL is an advanced Object-Relational database management system
(DBMS) that supports almost all SQL constructs (including transactions,
subselects, and user-defined types and functions).

Trustix has identified improper temporary file usage in the
make_oidjoins_check script. It is possible that an attacker could
overwrite arbitrary file contents as the user running the
make_oidjoins_check script. This script has been removed from the RPM file
since it has no use to ordinary users. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0977 to
this issue.

Additionally, the following non-security issues have been addressed:

• Fixed a low probability risk for loss of recently committed transactions.

• Fixed a low probability risk for loss of older data due to failure to
  update transaction status.

• A lock file problem that sometimes prevented automatic restart after a
  system crash has been fixed.

All users of rh-postgresql should upgrade to these updated packages, which
resolve these issues.
