Implemented in v11, attached.

Is this what you had in mind? It leaves a lot of the work to
postgres_fdw and it's almost unusable without postgres_fdw.

That's not a bad thing, but it makes the core functionality a bit
harder to test standalone. I can work on the core tests some more. The
postgres_fdw tests passed without modification, though, and offer a
simple example of how to use it.
