Reasonable, > but solveable with some external preprocessor/script too. Can you explain how an external preprocessor/script addresses the issue of %TYPE in a function definition? Presumably the preprocessor has to translate %TYPE into some definite type when it creates the function. But how can a preprocessor address the issue of what to do when the table definition changes? There still has to be an entry in pg_proc for the procedure. What happens to that entry when the table changes? You seem to be saying that %TYPE can be implemented via some other mechanism. That is fine with me, but how would that other mechanism work? Why it would not raise the exact same set of issues? Ian
