If I good undertend you.. You want select values from a array in separate
rows. Hmm see:
select o.val[1][1] from orders o where id=1 UNION ALL select o.val[1][2]
from orders o where id=1;
val
--- 1 2
(2 rows)
And you have selected first dimension of the array now. But it is terrible
method if you have a lot of dimensions and if you want search in array
(for this is '*=' operator ..etc.).
