improvements in this direction are for a separate patch.

This isn't about making FDWs more like local tables- indeed, quite the opposite. The question is if we should declare that WITH ORDINALITY will only ever be for SRFs or if we should consider that it might be useful with FDWs specifically because they are not unordered sets as tables are. Claiming that question is unrelated to the implementation of WITH ORDINALITY is rather... Bizarre. 

Thanks,
