If it doesn't take the same parameters then it's not the same function
at all, so that part is a nonissue. We'd have to disallow change of
return type as well.

Updating pg_proc wouldn't be hard. What's missing is a notification
mechanism that would cause cached copies of the function to get
replaced. A crude first cut could just ignore that issue and still be
extremely useful for development ...
