Re: db_index=True not working, and indexes in class Meta yes

Yes, exactly. Django doc tells they do the same. And they do, but if you do not specify db_index=False in field, both indexes are created.

what I suspect is happening here, you're telling django that it should have two indices for that particular column covering identical areas of responsibility.
