I think you've both understood what I said correctly. Note that I remain neutral on the question of whether or not checksums should be enabled by default. Perhaps I've missed the point entirely, but, I have to ask: How could there ever be false positives? With checksums, false positives are simply not allowed. Therefore, there cannot be a false positive, unless we define checksums as a mechanism that should only find problems that originate somewhere at or below the filesystem. We clearly have not done that, so ISTM that checksums could legitimately find bugs in the checksum code. I am not being facetious. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
