If you can't get your DBA to update from Oracle 8 to modern Oracle, you've got zip chance of persuading him to deal with Postgres, so I think you're wasting your time worrying about left-join syntax. After you waste a man-year or so on that, he'll just find something else to complain about. regards, tom lane
