Well, first, let me say that the above just seems wrong.  I can't think
of any valid reason why reserved shouldn't be allowed to equal max.  

I also assumed that pg_update would be attempting to connect as the
superuser.  Therefore, if you only allow a single connection from the
superuser and pg_upgrade is using it, that would seem fairly hard to
mess things up.  On top of that, that's also the risk of someone being a
superuser.  They will ALWAYS have the power to hose things.  Period.  As
such, I don't consider that to be a valid argument.
