Yes, but the result will be that anyone with a 2TB table will *never* convert it to the new format. Which means we can never deprecate that format, because lots of people will still be using it. I continue to assert that all of this sounds like 9.3 work to me. I'm really not keen on pushing through a hack which will make pushing in a long-term solution harder. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
