Well, that just says that we'd better reconsider *both* of those names. Frankly, neither of them is well chosen, and the fact that they currently sound unrelated is a bug not a feature. What about something like "max_overall_worker_processes" and "max_session_worker_processes"? 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
