Well, I'm not insisting on any particular method of getting there, but
if we're going to touch this area at all then I think "fix the replay
hazards" should be a non-negotiable requirement. We'd never have accepted
such hazards if CREATE DATABASE were being introduced for the first time;
it's only like this because nobody felt like rewriting a Berkeley-era
kluge.
