That happens to be exactly what Andres did for expression evaluation
in commit b8d7f053c5c2bf2a7e8734fe3327f6a8bc711755, and I think
generalizing that to include the plan tree as well as expression trees
is likely to be the long-term way forward here. Unfortunately, that's
probably another gigantic patch (that should probably be written by
Andres).
