I don't like phrasing it that way: if we are going to do this at all
then the number of reserved slots should be a configurable parameter.
If I were a DBA I'd want it to be at least two: figure one for a cron
job (doing backups, periodic vacuums, etc) and one for emergency
interactive superuser access. It definitely seems like something that
installations would have differing views about.
