Update all PostgreSQL ports to latest version.
Remove postgresql-contrib in favour for postgresqlNN-contrib.
This way we will get packages built, which is nice.
The PostgreSQL Project today released minor versions updating all active
branches of the PostgreSQL object-relational database system, including
versions 8.4.4, 8.3.11, 8.2.17, 8.1.21, 8.0.25, and 7.4.29. This release
fixes moderate-risk security issues with PL/perl and PL/tcl, as well as
a data corruption issue with standby databases. Users of any of these
three features should update their PostgreSQL installations immediately.
