In postgresq-7.0.3, I did:

cd contrib/array
make
make install

[I'm not certain the following is necessary, but if you get errors it might fix things]
psql -d yourdb -f array_iterator.sql
[or whereever install put it]

Then, just try something like:

select groname from pg_group g, pg_user u
where g.grolist *= u.usesysid and
u.usename = 'young' ;
groname
------------
supervisor
originator
operator
(3 rows)

showing that I'm in those three groups.

I hope this helps,
