Thanks, but the track table doesn't have a release column, but a medium column (the recording column doesn't help much either). I was eventually able to query the tracklist for a release using that table. The SQL query below gives an example for all releases by the artist 'AC/DC', sorted by release and position of the track on a release.
select r.id, r.name, t.name, t.position, t.length, m.name, m.position
from track t, medium m, release r
where r.artist_credit = 1352 -- 1352 corresponds to artist 'AC/DC'
and t.medium = m.id
and m.release = r.id
order by r.id, t.id
