My vision of ALTER FUNCTION is that it would let you change the function
body, and perhaps also the function language and attributes (isCachable,
isStrict). It would NOT allow you to change the function's parameter
types or return type, because that potentially breaks things that depend
on the function. To do that, you should have to create a new function.
