Don't give superuser privileges to anyone who's dumb enough to try such
things on a production database.
This is much like the fact that, say, root can trivially destroy any
Unix filesystem. You could imagine trying to put enough training wheels
on superuserdom to prevent such things, but it's not really practical
and any attempt would get in the way of many legitimate uses.
