It strikes me that it's not good if there isn't a recognizable "invalid" value for WAL locations. These bits of code show that there is reason to have one. Maybe we should teach initdb to start the WAL one segment later, and then 0/0 *would* mean "invalid", and we could revert these other hacks. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
