Subject: Bug with ORDER BY expression [ ASC | DESC ] ?

Hi,
I am doing the following select in PostgreSQL 7.2.1
select distinct on (o.sid,o.timepoint,o.lid,o.mid) o.sid,o.timepoint,o.lid,o.mid,o.value
from onfvalue o, tempreftime t
where o.sid=t.sid and o.timepoint=t.timepoint and o.lid=t.lid and o.mid=t.mid
order by o.sid,o.timepoint,o.lid,o.mid,o.entrancetime desc;
but the result is coming in ascending order.
There is no difference to
select distinct on (o.sid,o.timepoint,o.lid,o.mid) o.sid,o.timepoint,o.lid,o.mid,o.value
from onfvalue o, tempreftime t
where o.sid=t.sid and o.timepoint=t.timepoint and o.lid=t.lid and o.mid=t.mid
order by o.sid,o.timepoint,o.lid,o.mid,o.entrancetime asc;
Is this a bug or am I missing something?
Regards, Christoph
