Note that only one of the listed standbys is a synchronous standby at any given time though. That is, when you commit, the primary server will wait just for that one server to report that it has fsync'ed the WAL. (There is a patch being developed to change that so that you might be able to wait for more than one in a future release). -- Thomas Munro http://www.enterprisedb.com -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
