Please clarify me. autovacuum_vacuum_cost_limit is effectively 100 by default. You could raise it to 2000 or more. If that does not take care of your problems, set autovacuum_vacuum_cost_delay to 0. That will make autovacuum even more aggressive. Do *not* set autovacuum_vacuum_scale_factor to 0. That will just cause autovacuum to run all the time without getting anywhere. Sorry for trying to use irony in e-mail; I am aware I shouldn't do that. Yours, Laurenz Albe -- Cybertec | https://www.cybertec-postgresql.com
