I would expect the primary *performance* value in an "hstore
extension" to come from things that allow accessing data without
needing to "unbox" it.
(I remember the concept of unboxing from APL; it seems to have been
subsumed by object oriented terminology...

The big "win" comes not as much from type matching (which seems to me
like a morass, as you'll need the zillion Postgres types to cover all
the cases) as it comes from avoiding the need to take the "blobs" of
tuple data and re-parse them.
When confronted by a difficult problem, solve it by reducing it to the
question, "How would the Lone Ranger handle this?"
