I failed to resist the temptation to poke at this, and found that
indeed nothing seems to break if we just use one transaction for the
whole processing of postgres.bki. So I've pushed a patch that does
that. We're definitely down to the point where worrying about the
speed of bootstrap mode, per se, is useless; the other steps in
initdb visibly take a lot more time.
