7.3 says this:
NOTICE:  Adding missing FROM-clause entry in subquery for table "temp_hasil2"

which means that the query is invalid according to the SQL spec.  Later
versions are just being tougher about enforcing the spec.  If you are
happy with 7.3's interpretation of what the query means, try adding

>             (select max(B38.tglavd) from am382 B38, Temp_hasil2
                                                    ^^^^^^^^^^^^^
