and do you agree that I should turn CLUSTER ON ?
I have no problem to stop all tasks to this table at night and just
reload it
You don't turn it on; it's a one time operation that does a cleanup. It
is by far the easiest way to clean up the mess you have right now.
Moving forward, if you have max_fsm_pages set to an appropriate number,
you shouldn't end up back in this position again. But VACUUM along
won't get you out of there, and VACUUM FULL is always a worse way to
clean this up than CLUSTER.
