Ok, I get your argument when there is just one target server (cluster),
which is probably at least 99.9% of the use case in practice.
However, ISTM multiple ip & multiple hostname look pretty close.
I guess that the number of people that use these features is small, but
for these when things go wrong better messages are useful... so I would
see no harm to trigger the server introductory line when there are
multiples servers, whatever the reason why there are multiples servers.
