Show HN: Pg_insights – Convenient SQL for monitoring Postgres database health

This is an evolving collection of useful SQL for checking in on some important PG metrics. It's been a valuable resource recently at Lob to check in on our Postgres usage and health.

Heroku's pg-extras inspired this tool. pg_insights is useful for PG instances outside Heroku's hosted DB service. https://github.com/heroku/heroku-pg-extras
