Well you guys are right; the problem is that the query is actually more
complex, I tried to simplify it for the question, but ended up with a
trivial question...
Let's see if this example is better:

CREATE TABLE mytab
(
     num integer,
     num1 integer,
     num2 integer,
     mydate timestamp
);


select MAX(num), SUM(num1)+SUM(num2), date_trunc('day', mydate) from
mytab group by date_trunc('day', mydate)

but I also want the timestamp where MAX(num) happened for each day.
