This is a big hint that things are going wrong.  You need those quotes
in there, an "integer" is a plain number and not a date.


This one does work in the sense of selecting out the wrong host but it still produces nothing but NULLs!

SELECT h.id, r.id, r.start_date, r.end_date
  FROM hosts h
    LEFT JOIN (reservation_hosts m INNER JOIN reservation r
        ON m.reservation_id = r.id
AND (r.start_date,r.end_date) OVERLAPS ('2009-04-09'::date,'2009-04-10'::date))
      ON h.id = m.host_id
  WHERE h.id NOT IN (
    SELECT m.host_id
    FROM reservation r, reservation_hosts m
    WHERE r.id = m.reservation_id
      AND m.host_id IS NOT NULL
AND (r.start_date,r.end_date) OVERLAPS ('2009-04-09'::date,'2009-04-10'::date)
  ORDER BY h.id, r.start_date)
