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.
