Or a bug in the domain-constraints implementation.  plpgsql just
executes the input function for the datatype --- which is the same as
the input function for the underlying type.  There should probably be
some mechanism to make the input function for a domain type check the
domain's constraints.

[ thinks about it... ]  We added code to COPY to check domain
constraints on top of calling the type's input function, but I wonder
whether that wasn't the wrong way to go.  We'll have to hack everyplace
that calls an arbitrary input function, if we insist on that approach.
