13312	Add a way to customize the order_by() of null fields	Sergey Dobrov	Mariusz Felisiak	"Applying order_by on null=True fields gives different results on mysql and pgsql: pgsql thinks that NULL values are bigger than any and mysql that smaller. I think that this must be unified on all engines for prevent problems with portability. pgsql has additional parameter for this:

{{{
SELECT select_list
    FROM table_expression
    ORDER BY sort_expression1 [ASC | DESC] [NULLS { FIRST | LAST }]
             [, sort_expression2 [ASC | DESC] [NULLS { FIRST | LAST }] ...]
}}}

But I don't know how it on other engines."	New feature	closed	Database layer (models, ORM)	dev	Normal	fixed	ordering, order_by, null	contact@… serhiy.int@… markus.magnuson@… josh.smeaton@… github@…	Ready for checkin	1	0	0	0	0	0
