It'a a shame for me that I could not think of using subselects :-(

Hi,
I have created a table like this:
CREATE TABLE test (
b_date char(8),
active boolean,
id serial
);
and inserted some rows.
Now, what I want is to select the b_date which has the minimum "id" and
active=t.
A normal query would be :
SELECT b_date,min(id)
