I'm reading that the test falsified this assertion that we've enabled postgres
to run safely under an admin account.  Enabling safe use of admin accounts
entails fixing single-user mode.  (Alternately, one could replace the "vacuum
that database in single-user mode" errhint with a reference to some
not-yet-built alternative.  That sounds harder.)
