I think this is a fairly big oversight that should be fixed in the most backwards compatible way, so users don't need to change their code, or only have to change it minimally. I'm with Aymeric here. Does Django have visibility of the field constraints at insert/select queryset time? Ideally Django would handle the differences transparently. If that's not possible then we should have a migration or script that'll do the conversion on behalf of users once off.
./manage.py mysql-upgrade-microseconds && ./manage.py migrate ?
