Thanks for giving it another look.
I'm also quite happy with the patch now. The 2 plan changes are
explained. I have a patch on another thread [1] for the change in the
Merge Join plan. I'd like to consider that separately from this
patch.
The postgres_fdw changes are explained in [2]. This can be fixed by
setting fdw_tuple_cost to something more realistic in the foreign
server settings on the test.
I'd like to take a serious look at pushing this patch on the first few
days of August, so if anyone is following along here that might have
objections, can you do so before then?
