No, the whole point of domains is to restrict a datum (column, etc.) of a
certain type to a subset of the allowable values. But the data is still
of the same type, so it is generally inappropriate to treat it differently
in the client or anywhere else where type identity matters. If you dig
through the SQL standard, you will see this theme throughout.
