I think you're failing to explain yourself very well.  What you really
mean is that we should use cluster_name not application_name to determine
the name that a standby server reports to the master.

There's something to that, perhaps, but I think that the mechanism we use
for doing the reporting involves the application_name parameter passed
through libpq.  It might be a bit painful to change that, and I'm not
entirely sure it'd be less confusing.
