What bugs me the most about having IN() be faster than EXISTS() in
certain situations is that it ends up being counter-intuitive and not
really what you'd expect to happen. That being said, we can always tell
people that they can use IN() as a work-around for these situations. In
the long run, I think it's definitely worth it to spend a bit of extra
time in planning the query for this case. Not knowing what else is on
your plate for 8.4, I don't know where I'd rank this, but it wouldn't be
at the top.
Thanks,
Stephen
