This seems to work for me.  I used the snapshot from 3/28 on Solaris 8

SELECT service, count(*) AS GebruikersAantal
FROM tbtrouble GROUP BY service;
  service  | gebruikersaantal 
-----------+------------------
 Service 1 |                2
 Service 3 |                2
 Service 4 |                1
(3 rows)

SELECT service, count(*) AS GebruikersAantal
FROM vwtrouble GROUP BY service;
  service  | gebruikersaantal 
-----------+------------------
 Service 1 |                2
 Service 3 |                2
 Service 4 |                1
(3 rows)
