Title: filter out the relation_stats parameter

without this, if you use relation_stats in your configuration, this
happens:

```
CRITICAL 2014-01-16 00:20:27,655 19372 MainProcess MainThread newrelic_plugin_agent.plugins.postgresql poll L259 : Could not connect to PostgreSQL, skipping stats run: invalid connection option "relation_stats"
```

This is a major blocker for us to use the agent, so the sooner this can be released, the happier I'll be :)
