I would like to fetch statistics from a PostgreSQL-database (e.g. from pg_stat) using a custom SQL. This calls for custom metrics; but before fiddling with that: are there any repository for this? This has surely been done before, right? :)

I don't know of any open source plugin that fetches data from PostgreSQL.
That being said, our services department has created several such plugins in the past, so if you want help with it you can reach out to us through your account/delivery manager.
