24923	Aggregates in order_by should error out nicely	Anssi Kääriäinen	Tim Graham <timograham@…>	"Expressions are allowed in order_by, but aggregates don't currently work. Making them work would cause too much trouble when taking in account that you can already do
{{{
qs.annotate(agg=Sum('foo')).order_by('agg')
}}}
as opposed to
{{{
qs.order_by(Sum('foo'))
}}}"	Cleanup/optimization	closed	Database layer (models, ORM)	dev	Normal	fixed			Ready for checkin	0	0	0	0	0	0
