This works on 9.6.9 and 11.4:

luca=> with u as ( update t_all set id = 5 where id <= 5 returning *)
select * from u;
 id | ref_id
----+--------
  5 |      1
(1 row)

luca=> select version();
                                             version

 PostgreSQL 9.6.9 on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu
7.2.0-8ubuntu3.2) 7.2.0, 64-bit
(1 row)


However, I know for sure that UPDATE has some restrictions on the
table aliasing (at least, they are not used as for a SELECT), so the
problem could be in the real query you are executing.
It works with or without the order by.
