Thanks Rickard
Max may not work as not all the data is numerical. However I will give the contrib/cross-tab a go!

Don't forget the provided crosstab functions (in contrib/). If you don't
want that, you could aggregate your results:
SELECT content_object_id, MAX(xpos), MAX(ypos), ...
FROM (
<your query here>
) AS raw
GROUP BY content_object_id;
