No databases will do this automatically for you (whether you use mysql,
sqlite, postgresql or something else), so you need to create multiple
queries:

mysql example:

$query = "insert into users(username) values ('my_username')";
mysql_query($query); $userid = mysql_insert_id();

$query = "insert into table2(userid) values('$userid')"; 

postgres example:

$query = "select nextval('user_sequence') AS nextid"; $result =
pg_query($query); $row = pg_fetch_assoc($result); $userid = $row['nextid'];

$query = "insert into table2(userid) values('$userid')";

Hi,

Yay a postgres question! :D hee hee

*The question is* : how can I force that the result of the col payed 
to be zerro "0" insted of nothing (NULL)

and the order will be in way that the zerro's values comes first.
and the result will be:

 sum | payed | to_pay
-+---+
 25 | 0 |  0
150 |   150 |  0
175 |   150 | 25



COALESCE will do it for you:

SELECT SUM(c_price) as sum,(SELECT COALESCE(SUM(d_price), 0) FROM d 
WHERE a_id=t1.a_id ) AS payed, SUM(c_price)-(SELECT 
COALESCE(SUM(d_price), 0) FROM d WHERE a_id=t1.a_id ) AS to_pay FROM c 
AS t1 group by a_id order by payed;


 sum | payed | to_pay
-+---+
  25 | 0 | 25
 150 |   150 |  0
 175 |   150 | 25
(3 rows)
