Where are the WAL > records that the "loadable rmgr" processes going to come from? There is ample reason to do this. I covered this in my first post, please re-read up thread. You have commented on this post already, so I'm suprised by your comments. Rmgr functions only execute during recovery, that is their role in life. Except when we have WAL_DEBUG enabled they are never called elsewhere. -- Simon Riggs www.2ndQuadrant.com PostgreSQL Training, Services and Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
