Tigthen binary receive functions so that they reject values that the text
input functions don't accept either. While the backend can handle such
values fine, they can cause trouble in clients and in pg_dump/restore.
This is followup to the original issue on time datatype reported by Andrew
McNamara a while ago. Like that one, none of these seem worth
back-patching.
