I missed this whole thing, and eventually I have to circle back to it.
I could do it this week. Could you (or someone else familiar with the
useful benchmarks) give me more detail on how to replicate one case
where things should improve? I can do that, and I have a lab full of
hardware if it's easier to spot on one type of server. That exercise
will probably lead to a useful opinion on the feature in its final form,
any associated GUC, tunables, and necessary level of associated
documentation in a day or two.

This is a pretty low bar, right? Examples and documentation sufficient
for just me to catch up is not asking for very much. If it isn't
possible to do that in a very short period of time, it would not bode
well for broader consumption.
