well reordering 1000 objects in scala/java is fast or doing map/flatmap/filter or put them into a map, however with django orm it's not. not a problem in python tough since when you directly use pg from python it retuns a iterator which is faster when you directly put everything correctly in your list. problem with django orm is that it copies it into a list structure etc. pp. (at least pre 1.4)
