1s? I don't think that setting it to 1s would ever be a good idea, but I don't want to tie users' hands if they know better than I do. Also, unless we use 1s granuarity, users can't set it to values like 45s, which is more reasonable. I can't see any circumstance under which sub-second values would ever make sense. Now ... can we decrease CPU overhead (wakeups) if we only check once per minute? If so, there's a good argument for making 1min the minimum. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
