If you run a normal vacuum often enough, you shouldn't need to regularly
run vacuum full.

Hmm, here we have a certain table, sort of FIFO, rows get inserted all the time, lay there for a couple of hours and get deleted "the other end around". We run normal vacuum almost constantly, but the table keeps growing. We had to implement a 'vacuum full' once a week to keep it under control.

What is the size of your database, how many tables do you have and what are your FSM settings?
