Does this also happen when you explicitly name the columns?

   SELECT table1.id, ..., table2.id, ...
   FROM table1, table2

Or if that doesn't help, try if a column label with the AS
clause works:

SELECT [ ALL | DISTINCT [ ON ( expression [, ...] ) ] ]
    * | expression [ AS output_name ] [, ...]
http://www.postgresql.org/idocs/index.php?sql-select.html

  SELECT table.id AS id1, ..., table2.id AS id2
  FROM table1, table2

And then rs.getString("id1");

I think both solutions should work. Please let us know if they
don't.
