Hi,
I don't think that's a bug. While it's uncommon for builtin functions
to have named arguments, there's a few others in pg_catalog.
Also, GRANT/REVOKE works with named parameters as well:
CREATE FUNCTION exec(text) RETURNS text LANGUAGE plpgsql VOLATILE AS
$f$BEGIN EXECUTE $1; RETURN $1; END;$f$;
select exec(format('grant all on function %I(%s) to public', proname,
pg_get_function_arguments(oid))) from pg_proc where proname ~ 'uuid';
exec
-----------------------------------------------------------------------------
[...]
grant all on function uuid_generate_v3(namespace uuid, name text) to public
grant all on function uuid_generate_v4() to public
grant all on function uuid_generate_v5(namespace uuid, name text) to public
(22 Zeilen)
What issue specifically do you have with this?
