Subject: [PATCH] Add connection messages for streaming replication.
 log_connections was broken for a replication connection and no messages were
 displayed on either standby or primary, at any debug level. Connection
 messages needed to diagnose session drop/reconnect events. Use LOG mode for
 now, discuss lowering in later releases.
