HOW TO FIND SHITTY INDEXES: https://gist.github.com/jberkus/6b1bcaf7724dfc2a54f3
==-=-=-
OK: this is the best query to use to find non used indexes
Run it and look for any indexes that are *not* primary keys (name ends in pkey, want ones that end in idx which are mine)
that have zero in idx_scan, that means they are completely unused (if a lot of full test runs that excercise all routes and features have happened prior to checking)
