Hmm, I dunno if my opinion counts as "wisdom", but what I was arguing for
there was that we should print stuff if it's potentially invoked by a
run-time decision, but not if it was excluded at plan time. I'm not
totally clear on whether jitting decisions are fixed by the plan tree
(including its cost values) or if the executor can make different
decisions in different executions of the identical plan tree.
If the latter, then I agree with Justin that this is a bug.
