I reviewed your patch and used it in my TPC-H benchmarks. It is still
WIP. Will you improve this patch?
I also want to say that, in my opinion, Horiguchi-san's version seems
preferable: it is more structured, simple to understand, executor-native
and allows to reduce FDW interface changes. This code really only needs
one procedure - IsForeignPathAsyncCapable.
