A final (& possibly best) option, is:

Select
MDT.GETFILE,
[anything else from 'best' record]
From
(Select Distinct SID From LOGS) as S,
(Select * From LOGS L Where L.SID = S.SID
Order By DATETIME Asc Limit 1) as MDT

But unfortunately PG 7.1 does not allow this - the second select can not
reference the first select. I have not tried it in 7.1.2.
