Probably not, since it sounds like your queries are typically not as
trivial as the ones in Guillame's test case.  IOW there will be some
slowdown but it's likely to be in the noise for you, and also very
likely made up by improvements elsewhere.  The test case is in the
unfortunate position of not being helped materially by *any* of the work
we've done for 8.3.
