# 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_ view. 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)
