Advice returning data as an array

I have the following query that works the way I need:
SELECT '20090812' AS date, sum(in_oct) AS bytes, sum(in_pkt) AS pkts, 'appl'
AS name, ARRAY['appl'] AS fields, CAST((LEAST(src_port, dst_port)) AS
varchar) as fieldVal FROM flow_history.flows_20090812 GROUP BY fieldVal
ORDER BY bytes DESC LIMIT 20;

My issue is that I need to get the fieldVal to return as an array and be
fieldVal[1]. Any suggestions?

Thanks,
Woody
