Hi team,
Attaching a proposed patch to make it more explicit that max_parallel_maintenance_workers does not apply to autovacuum, which does not use parallelism. I personally believe that this could be made clearer.
Sources of autovacuum not running parallelism:
1)
postgres/src/backend/postmaster/autovacuum.c, line 2913 at time of writing:
/* As of now, we don't support parallel vacuum for autovacuum */
2)
Best regards,
Matthew
