Yep, from a quick glance I don't think this will require a lot of coordination, just some rebasing. My work is mainly focused on instrument.c and the executor, vs this here happens mainly in explain.c and the node-type specific instrumentation. I do also have a patch set that I haven't posted yet that reworks how we do parallel worker instrumentation reporting more broadly, but I don't see any immediate problems that would arise. I'm aiming to do a proper review pass on this patchset as well today/tomorrow, but wanted to comment on that quickly :) Thanks, Lukas -- Lukas Fittl
