One problem is that HAVING really works on entire groups at a time
(including aggregated data for the group) not on pieces of the group.
However, I think one might be able to fake it with an array accumulating
aggregate like the one from
http://www.postgresql.org/docs/current/static/xaggr.html
and a query like:
SELECT object_id FROM image GROUP BY object_id HAVING
NOT(1 = ANY(array_accum(sort_order))).
