That's an interesting point. I wonder whether this whole thing will be useless or even counterproductive after (if) Heikki's CSN-snapshot patch gets in. I would certainly not mind reverting the PGXACT/PGPROC separation if it proves no longer helpful after that. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
