I was assuming that if the code went through the trouble to buffer the shared page to get a "stable, non-changing" copy to use for checksumming/writing it, it would write() the buffered copy it just made, not the original in shared memory... I'm not sure how that write could be in-consistent. a. -- Aidan Van Dyk Create like a god, ai...@highrise.ca command like a king, http://www.highrise.ca/ work like a slave. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
