Here is an updated patch.  Changes are:

* Added docs on FDW APIs.
* Added/tweaked some more comments.
* Fixed a bug and typos pointed out by Justin.
* Added an assertion to ExecAppendAsyncBegin().
* Added a bit more regression test cases.
* Rebased the patch against HEAD.

I think the patch would be committable.

Best regards,
