Oh, I agree.  Since we have a separate WALSender limit, it seems
counter-intuitive and difficult-to-admin to have the WALSenders also
limited by superuser_connections.  They should be their own separate
connection pool, just like the other "background" processes.

However, if this was somehow infeasible, it wouldn't be hard to
document.  That's all.
