The synchronous standby will be the first standby named in this list that is both currently connected and streaming data in real-time (as shown by a state of streaming in the pg_stat_replication view). Other standby servers appearing later in this list represent potential synchronous standbys.... The name of a standby server for this purpose is the application_name setting of the standby, as set in the primary_conninfo of the standby's walreceiver. There is no mechanism to enforce uniqueness. In case of duplicates one of the matching standbys will be chosen to be the synchronous standby, though exactly which one is indeterminate. The special entry * matches any application_name, including the default application name of walreceiver. " So I would check the pg_stat_replication view to see if Postgres is seeing the standby as streaming. > > Thanks > VB -- Adrian Klaver adrian.klaver@xxxxxxxxx -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
