We aren't going to hold up 9.3 until that particular bit of pie in the sky lands. Indeed I don't expect to see it available in the next couple years either. When we were looking at that seriously, two or three years ago, arbitrary page format changes looked *hard*. The idea of bumping the page format version number to signal a checksum algorithm change might work though. 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
