Blazer is my favourite BI tool by a country mile. It does all I want with no fuss, is a breeze to set up and it's so much faster and more efficient than any of the other BI tools I've tried.

PgHero is also from him I believe. Very helpful to identify slow queries in production, remove duplicate indexes, see missing indexes, keep an eye on table size, etc.
