I can't see a reason to disallow login, because read-only transactions
can still run in such a situation --- and, indeed, might be fairly
essential if you need to inspect the database state on the way to fixing
the replication problem.  (Of course, we've already had the discussion
about it being a terrible idea to configure replication from inside the
database, but that doesn't mean there might not be views or status you
would wish to look at.)
