I think this is introducing complication and race conditions to solve a problem that no one will really care about. Just let people change the filename at SIGHUP and document that doing that on-the-fly may cause stats queries to fail for a short interval. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
