If you don't like CREATE RULE, try having your test program send just
Parse messages, and not Bind/Execute.  I still dislike the idea of
exposing a fundamentally-broken-and-useless variant of EXPLAIN in order
to have a test harness for a variant of performance testing that hardly
anyone cares about.  (There is no real-world case where the performance
of the parser matters in isolation.)  If we do that, it will be a
feature that we have to support forever, and possibly fix bugs in ---
what if the system crashes because the rewriter wasn't invoked, for
example?
