PostgreSQL plugin

This postgresql plugin provides metrics for your postgres database. It currently works with postgres versions 8.1+. It uses data from the built in pg_stat_database and pg_stat_bgwriter views. The metrics recorded depend on your version of postgres. See table:

pg version      9.2+   9.1   8.3-9.0   8.1-8.2   7.4-8.0(unsupported)
