sum() - unexpected results.

Hi,

I got some unexpected results from a sum().. just wondering
if it's a bug of any sort, or if i just should have been expecting it..

SELECT sum(foo) FROM mytable WHERE active = 1;

Now lets say that no rows are active = 1, then this query returns
1 blank row..

I would have expected either
    1:    a result of zero
        or
    2:     zero rows returned..

oh, btw this is pgsql 7.0.2 on fbsd.

anyone ?
