OK, *now* we're on the same page. This sort of experimentation is
exactly what I'm talking about: we'll certainly want to rewrite the code
once we have better infrastructure, but it's necessary to write some
throwaway code while we're learning what infrastructure FDWs want.
(I find it a bit weird btw that you seem to be doing that at execution
time not plan time...)
