That's not a valid test. In that scenario, you're going to hold all
the locks acquired by the planner, all the locks acquired by the
rewriter, and all the locks acquired by the executor, but when using
prepared queries, it's possible to execute the plan after the planner
and rewriter locks are no longer held.
