Seems like rather a large hole in the ability to detect corruption. In particular, this again assumes that you can accurately locate all the hint bits in a page whose condition is questionable. Pick up the wrong bits, you'll come to the wrong conclusion --- and the default behavior you propose here is the wrong result. 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
