In the following example, the HAWQ query filters the `delivery_city`
partition `Sacramento`. The filter on `item_name` is not pushed down, since it
is not a partition column. It is performed on the HAWQ side after all the data
on `Sacramento` is transferred for processing.
``` sql
-postgres=# SELECT * FROM pxf_sales_part WHERE delivery_city = 'Sacramento'
AND item_name = 'shirt';
+postgres=# SELECT * FROM pxf_sales_part WHERE delivery_city = 'Sacramento'
AND item_name = 'cube';
