Discussion from IRC:
{{{
[02:24am] I don't see a test case here that emulates the failures seen
when the previous (committed then reverted) approach. Am I just missing
it?
[09:26am] jacobkm: I also can't say I'm particularly happy with the patch,
particularly iterating over the qs in distinct_choices().
[09:26am] chars:It's pretty hard to test for me. It's a case where
Postgres can't compare the values.
[09:26am] chars: So it can't test for uniqueness
[09:26am] jacobkm: It also needs additions to documentation to mention
that Q() objects are acceptable in limit_choices_to.
