If you're feeling like a DBA cowboy, become superuser and issue a direct UPDATE against the prosrc column of pg_proc, being careful not to update rows that aren't the functions you want to hit.
Slightly saner would be to read pg_proc and construct CREATE OR REPLACE FUNCTION commands that you then EXECUTE. The latter, if not done as superuser, would at least ensure you didn't accidentally break any functions you don't own.
In either case, I'd practice against a test copy of the database before doing this live ...
