DESCRIBESQuestion

CAUSED_BYRootCause

autovacuum may run for days and not complete in time — one of the tables is massive (~5 billion rows). Tension: When MultiXactID is close to being exhausted, auto-vacuum should kick in and prevent the wraparound. Outcome: increasing `autovacuum_vacuum_cost_limit` will make autovacuum pause less often and thus make it faster.

FIXED_BYSolution

increasing `autovacuum_vacuum_cost_limit` will make autovacuum pause less often and thus make it faster — If autovacuum is too slow, you should speed it up. Tension: autovacuum may run for days and not complete in time. Outcome: increasing `autovacuum_vacuum_cost_limit` will make autovacuum pause less often and thus make it faster.

FIXED_BYSolution

you should give autovacuum enough memory — In addition, you should give autovacuum enough memory so that it runs as fast as it can. Tension: autovacuum may run for days and not complete in time. Outcome: by raising `maintenance_work_mem`.

FIXED_BYSolution

the only solution is to partition the table — If you still don't get done in time with all these adjustments. Tension: Then autovacuum can run on all partitions in parallel. Outcome: you will probably need to increase `autovacuum_max_workers`.

FIXED_BYSolution

If that is still not enough, perhaps it helps to start cleanup earlier — If that is still not enough. Tension: autovacuum may run for days and not complete in time. Outcome: This is done by lowering `autovacuum_multixact_freeze_max_age` for that table.
