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.
