PFA patches for postgres_fdw join pushdown, taken care of all TODOs in
my last mail.

Here is the list of things that have been improved/added new as compared
to Hanada-san's previous patch at [1].

Great!  Thank you for working on that!  I'll review the patch.

I will be working next on (in that order)
1. eval_plan_qual fix for foreign join. (Considered as a must-have for 9.6)
2. Pushing down ORDER BY clause along with join pushdown
3. Parameterization of foreign join paths (Given the complexity of the
feature this may not make it into 9.6)

As discussed internally, I think #3 might have some impact on the overall design of the EvalPlanQual fix, especially the design of a helper function that creates a local join execution path for a foreign join path for EvalPlanQual. So, IMO, I think the order is #1, #3, and #2 (or #3, #1, #2).

Best regards,
Etsuro Fujita
