There are no cases at present where this matters, and no proposed patches (that I know of) that would make it matter. If an individual rmgr needs control of what happens during a given operation, it wouldn't use XLOG_NEWPAGE to represent the operation. End of problem. You haven't provided any convincing argument why this needs to be changed globally. 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
