Out arguments name of "pg_identify_object_as_address" function in 9.5.14 and 11beta3

Two of the out arguments name of function
"pg_identify_object_as_address" are not as documented.
Documentation says "name" and "args", but function returns
"object_names" and "object_args".

This query shows what the function returns:
select (pg_identify_object_as_address(classId, ObjId, objSubId)).*
from pg_depend where classId <> 0;

Thanks,
