I would rather take CONVERT USING out altogether, than have an
implementation that so clearly disregards the spec as to not even return
a compatible datatype.
Other than the fact that it's supposed to return varchar, the spec's
description of what it converts to what seems about as clear as mud.
I suspect however that it can't really be implemented properly without
support for per-value (or at least per-column) encoding, which is
something we're nowhere near having. Maybe we *should* take it out
instead of using spec-defined syntax for a behavior that we made up
out of whole cloth.
