Hi Curtis,

Looking at the code you just posted, you have this line here:

	geometries := array_append(geometries, temp_geom);

but I can't see where temp_geom is being set within your PLPGSQL
function? Should it be the_geom? Another trick would be to add something
like:

	RAISE NOTICE 'geometries count: %', array_upper(geometries, 1);

which should show the size of your arrays increasing as the function
runs.


HTH,

Mark.
