Why don't you make it simple and just use row_number() from 8.4... It can be
simplified as:
select row_number() over(), i, p from prueba limit 5;
I know the use of WF. What surprised me, is the difference between

hi people!
I have this test query to simulate rownums in 8.3:
SELECT
(select count(i)+1 from prueba
where i xi.i
) as rownum, i, p
FROM prueba xi limit 5;
Devuelve , que esta bien:
1;1;299361
2;2;421127
3;3;166284
4;4;458945
5;5;81619
But in 8.4 throws this:
postgres=# SELECT
postgres-#
