I was wondering why you wanted a non-complaining DROP. I mused
whether in was in preparation for an unconditional CREATE of a
table of the same name, and wondered whether an UPGRADE TABLE
was a satisfactory alternative (UPDATE TABLE would create the
table if it didn't exist and transmogrify it in a generally
upwards compatible way if it did).

The more general point is that in order to evaluate an extension,
it is important to understand what problem it purports to solve,
and that a statement of the problem sometimes leads to a different
but satisfactory solution.

And, of course, to avoid agreeing with you if at all possible
(Jason, that's a joke).
