Would be a good idea to check any PostgreSQL installations (full, embedded, and drivers).

The following new versions are available:
7.3.15, 7.4.13, 8.0.8, 8.1.4

Updated drivers for ODBC, Ruby, Perl, .Net, and C++ will be released shortly.

I'll update the diary with info on any good tools to test installations for this issue.
