if you are using 8.3+ and are wiling to make a composite type:
create table person_t(email text, phone text, address text);
select person_id, array_agg((email, phone, address)::person_t) from
person group by 1;
or, detail fields are in another table:
select person_id, (select array(select (email, phone,
address)::person_t) from detail where person_id = p.person_id) from
person_t;
