And it's easy to pretend it's already coded this way if you're motivated
enough.  Just find a schema name that's not already existing:

dim=# set search_path to public, utils;
SET
dim=# select pg_describe_object('pg_proc'::regclass, 16602, 0);                     pg_describe_object
    
 
---------------------------------------------------------------function
unaccent_lexize(internal,internal,internal,internal)
(1 row)

dim=# begin; create schema dummy; set local search_path to 'dummy'; select pg_describe_object('pg_proc'::regclass,
16602,0); rollback;
 
BEGIN
CREATE SCHEMA
SET                        pg_describe_object                          
---------------------------------------------------------------------function
utils.unaccent_lexize(internal,internal,internal,internal)
(1 row)

ROLLBACK
