Juerg, is a_id your primary key?  My examples are based on this
assumption, but if it is not, you still get the point, which is:
You can't use SELECT * here.

If you know the new a_id in advance:
   INSERT INTO auftrag (a_id, col2, col3, ...)   SELECT '67890', col2, col3, ...     FROM auftrag    WHERE a_id =
'12345';

If a_id is a serial or in any other way supplied automatically by a
DEFAULT clause or a trigger:
   INSERT INTO auftrag (col2, col3, ...)   SELECT col2, col3, ...     FROM auftrag    WHERE a_id = '12345';

HTH.
