Your query doesn't call st_dwithin only 320000 times. Because you test
every possible combination of polygons you actually calls the function
320000*320000 times. So it might be understandable. But it sounds quite
long anyway.
PostGIS 1.5 should handle this better too. Especially if the polygons is a
little bit complex with many vertxes upgrading might give quite a big
difference.
