Not really. AFAICS the only point is to catch storage-system malfeasance. It's barely possible that checksumming would help detect cases where we'd written data meant for block A into block B, but I don't rate that as being significantly more probable than bugs in the checksum code itself. Also, if that case did happen, the checksum code might "detect" it in some sense, but it would be remarkably unhelpful at identifying the actual cause. regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
