A new gem to help monitor Postgres performance in standalone instances

I just released my own gem for querying Postgres Databases for performance issues. I had used Heroku PG Extras and the Go Boundless New Relic Postgres plugin previously. Each are excellent tools with a lot of overlap. The holes for each-- hosting on Heroku needed for PG Extras and the lack of visibility into the queries themselves on New Relic-- pushed me to write this gem. My aim is to build an engine on it that will display the stats in screens that can be plugged into an application. We'll see how that goes.
