I'm a bit busy with other matters at the moment, so I'll probably look
at it later. One question is whether we should make use of
exec_eval_expr() by representing the RAISE parameter list as a list of
expressions (each of which would likely be simple enough to evaluate via
ExecEvalExpr()), or whether we want to extend exec_eval_expr() to handle
  expressions that yield multiple attributes.
