> Seems like overkill. Let's just reduce the values a bit. Agreed. How about max_worker_processes = 8 as before, with max_parallel_workers of maybe 6? Or just set them both to 8. I'm not sure that the out-of-the-box configuration needs to leave backend slots locked down for non-parallel worker processes. Any such process would require manual configuration anyway no? regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
