Log message:
    Code review for domain-constraints patch.  Use a new ConstraintTest node
    type for runtime constraint checks, instead of misusing the parse-time
    Constraint node for the purpose.  Fix some damage introduced into type
    coercion logic; in particular ensure that a coerced expression tree will
    read out the correct result type when inspected (patch had broken some
    RelabelType cases).  Enforce domain NOT NULL constraints against columns
    that are omitted from an INSERT.
