That's IMHO a too specific case to do it generally with the rule system. Should be some kind of constraint handled by the parser in putting an UPPER() func node around the targetlist expression. There could be more general support implemented, in that a user can allways tell that a custom function should be called with the result of the TLE-expr before the value is dropped into the tuple on INSERT/UPDATE.
