Uh, what?  CAST() is not about external representations of values, and
overloading it for that purpose doesn't seem like a particularly good
idea: you'd have to figure out what the conversions meant inside SQL as
well as externally.  Also, maybe I missed something, but a different
representation of individual data values within a COPY wasn't what we
were after here.
