I don't trust the news client I was using. So will answer again from
the Netscape version; This worked for me:
I have a table, sis, with schema:
Table "sis"
Column | Type | Modifiers
--------+--------------------------+-----------
time | timestamp with time zone |
stat10 | integer |
ipf10 | real |
ipf30 | integer |
select date_part ( 'doy',time ) as jday, max ( time ) from sis group by jday
(doy means day of year, which I called jday)
