get_next_by_FIELD returns itself if it is the last item, under postgres

[matt@…]

Sometime in the last few days get_next_by_FIELD seems to have broken under Postgresql. Calling get_next_by_published, where published is a DateTimeField(auto_now_add=True), on the latest item returns that same item again. e.g.

>>> x = Post.objects.all()
>>> x
... [<Post: #3 (2006-08-23)>, <Post: #2 (2006-08-20)>, <Post: #1 (2006-08-18)>]
>>> x[0]
... <Post: #3 (2006-08-23)>
>>> x[0].get_next_by_published()
... <Post: #3 (2006-08-23)>

Works fine under MySQL (passes all tests, and I don't see the problem). Unfortunately I don't have enough postgres access to run the tests there.

Ok, problem seems to have gone away...
