Import TIGER data into a temporary table first that later replaces the current location_property_tiger table. This way index creation on the table can be delayed until after the import which should speed up the import and result in significantly smaller indexes. Also removed index on parent_place_id as it is covered by idx_location_property_tiger_housenumber_parent_place_id.
