It seems we can choose freely between these two implementations -- I
mean I don't see any upsides or downsides to either one.
The current one has the advantage that it never makes the datadir
"dirty", to use Kyotaro's term. It verifies that the creation/drop form
a pair. A possible downside is that if there's a bug, we could end up
with a spurious PANIC at the end of recovery, and no way to recover.
