* delete_function - clean up as much as possible of a stale function cache * * We can't release the PLpgSQL_function struct itself, because of the * possibility that there are fn_extra pointers to it. We can release * the subsidiary storage, but only if there are no active evaluations * in progress. Otherwise we'll just leak that storage. Since the * case would only occur if a pg_proc upd

 * twice.
