If archive_mode is off and max_wal_senders = 0, then the WAL that's being generated won't be usable for streaming anyway, right? I think this is another manifestation of the problem I was complaining about over the weekend: there's no longer a single GUC that controls what type of information we emit as WAL. In previous releases, archive_mode served that function, but now it's much more complicated and, IMHO, not very comprehensible. http://archives.postgresql.org/pgsql-hackers/2010-04/msg00509.php ...Robert -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
