Problem extending a model with ManyToMany field

Currently, syncdb command will only create ManyToMany tables for a field if the model that field belongs to are newly created. For example, if I first have:
class A(models.Model): foo = ...
Then I run python manage.py syncdb, it will create a table for A model.
Then I add a new field to this model, say:
class B(models.Model): ... class A(models.Model): foo = ... bar = models.ManyToManyField(B)
Then I run python manage.py syncdb again, it won't create the needed ManyToMany table for me, the only way to have this table created is to drop the previously created table for A first, then let syncdb to create them for me again. I think it is inconvenient and need to be fixed.
