The APIs seem to be cleaner. The previous ones might be too straight
implementation of the SQL standard.

But I have some questions about the new APIs: 1. Doesn't FdwPlan need to inherit Plan struct? 2. Doesn't FdwPlan need
tosupport copyObject()? 3. If "Datum *values, bool *isnulls" is the better interface,    why do we use TupleTableSlot?
Wemight have the similar issue    in the index-only scan; it also handles virtual tuples.
