That sounds more like FOREIGN VIEW and FOREIGN FUNCTION to me, where you could have the whole control of the local/remote boundaries. I mean that when planning a query using a FOREIGN VIEW it would probably make sense to consider it as a CTE as far as the optimizer is concerned. About FOREIGN FUNCTION, that would allow to inject arbitrary parameters anywhere in the remote query when doing SQL functions. We have a very nice version of FOREIGN FUNCTION already, that's plproxy.
