If I remember well, we discussed at some point with you and charettes about
removing the string version (as opposed to callable) of RunPython, if we do it,
it may be better to do it early on in the release cycle.

For some reason MyModel.objects.create() returned an object with pk=None,
I could confirm the object was created with a call to MyModel.objects.all().
I'm not totally sure if it's a bug or a side effect of the fake ORM.

I was bitten quite badly by the fact that custom Manager and custom save()
methods aren't called, https://github.com/django/django/blob/master/docs/topics/migrations.txt#L296-L297

20:15 loic84: akaariai: what's your opinion no the recent ML thread regarding custom index types?
20:18 akaariai: loic84: write the SQL by hand... Or, maybe you could have a VirtualField that just creates indexes for you.
20:20 loic84: akaariai: I've been thinking about integrating PG arrays and JSON support in my projects.
