Hmm, I think the best idea is to save 2 bytes off the WAL header for all records, so there are no wasted bytes on 64bit or 32bit. That way the potential for use goes away and there's benefit for all, plus no argument about how to use those bytes in rarer cases. I'll work on that. And then we just put the originid on each heap record for MMR, in some manner, discussed later. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
