IMO, the 'right' way to do functions, especially if you have a lot of
code to deal with, is to keep your function bodies in .sql text files
and properly checked into a SCM. If you have to do a major name
change, then you can use standard code refactoring techniques and
re-apply the functions. Querying the pg_proc table (as damien noted)
is a way to search after the fact, but having to do that suggests
you're using the database to manage your code.
