My thinking would be that pg_dumpall should be hard-wired for template0
(just like it is for template1..) and that we should *not* be excluding
databases that are marked as datallowconn = false.. That said, it's not
clear to me what to do there instead. Maybe throw an error or a
warning? The point of pg_dumpall is to dump *all* the databases and at
least the manpage doesn't appear to say anything about "but ignores
databases with datallowconn = false".

I agree with this, with regard to template0.
