Then you need to keep the user-visible identifier of said function (schema+name+input argument types - you'd probably want to incorporate version into the name) in your user-space code.  Exposing runtime generated oids to user-space is not something I can imagine the system supporting.  It goes against the very definition of "implementation detail" that user-space code is not supposed to depend upon.
