I've seen double-bit errors in Internet routing which canceled each other out (the Internet checksum is just a sum, not a CRC, so this happens with some probability once you've got bit errors with a multiple-of-16 periodicity). -- Florian Weimer <[EMAIL PROTECTED]> BFK edv-consulting GmbH http://www.bfk.de/ Kriegsstraße 100 tel: +49-721-96201-1 D-76133 Karlsruhe fax: +49-721-96201-99 -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
