querying arrays

Hi,

I stucked upon the following situation:
create table test (
n int[] );

insert into test values (

'{1,2,3,4}'

);

now I need a query that returns all four numbers in different variables,i.e.

an array like n[1],...,n[4]

I tried queries like

select test.n from test which returns {1,2,3,4}

or

select test.n[i] from test, where i is 1,2,3 or 4 which each returns 1,2,...

What I'm looking for is a query that returns four rows with one number in each

result index. Can anyone help?
