Two vulnerabilities have been reported in PostgreSQL, which can be exploited by malicious users to cause a DoS (Denial of Service) or potentially gain escalated privileges.

1) Missing validation of arguments supplied to the functions supporting client-to-server character set conversion can be exploited by unprivileged users when calling the functions from SQL commands.

The vulnerability affects versions 7.3.* through 8.0.*.

2) The contrib/tsearch2 module misdeclares the return type of several functions, which breaks the type safety of "internal". The impact has reportedly not been investigated, but can at least crash the backend.

The vulnerability affects versions 7.4 and later with the contrib/tsearch2 module installed.

Solution
Update to version 8.0.3, 7.4.8, 7.3.10, or 7.2.8.
