REVOKE PRIVILEGES in SQL tab of selected function

Let's say we have this function:

CREATE OR REPLACE FUNCTION public.test(in_value character varying) RETURNS
character varying

LANGUAGE 'plpgsql' COST 100.0 VOLATILE LEAKPROOF SECURITY DEFINER

AS $$

BEGIN

RETURN in_value;

END;

$$;

ALTER FUNCTION public.test(character varying) OWNER TO user_group_1;

REVOKE ALL PRIVILEGES ON FUNCTION public.test(character varying) FROM
public;

GRANT EXECUTE ON FUNCTION public.test(character varying) TO user_group_2;

Now let's see it with pgAdmin 3:

...

GRANT EXECUTE ON FUNCTION public.test(character varying) TO user_group_1;

GRANT EXECUTE ON FUNCTION public.test(character varying) TO user_group_2;

REVOKE ALL ON FUNCTION public.test(character varying) FROM public;

And now with pgAdmin 4:

...

GRANT EXECUTE ON FUNCTION public.test(character varying) TO user_group_1;

GRANT EXECUTE ON FUNCTION public.test(character varying) TO user_group_2;

Like you can see the revoke of public access is not included in pgAdmin 4 in
SQL tab.

It would be nice to have the whole list of privileges changes there. Because
for example when I copy the code and execute it on another database, then
everyone has access to it!
