Firstly, with autovacuum you really don't need to be running VACUUM
FULL anyway. VACUUM FULL is actually quite inefficient, you're better
off having higher FSM settings and leaving it to autovacuum.
For more info, post the actual output of VACUUM VERBOSE. That displays
enough info to get to the cause.
Have a nice day,
