Since the meaning of the first message is different between 8.4 and 9.0
(in 8.4, the normal connection to the database 'replication', in 9.0, the
connection for replication from the standby server), we would still need
to change the existing scripts. No?
What is worse is that we can connect to the real database 'replication'
in 9.0. So we might be unable to discern that normal connection from the
replication connection by seeing the first message.
