Switching the database is quite fun with Django. In my case I’m slowly migrating my sites from MySQL to Postgres.

1. manage dumpdata will produce a database independent XML or JSON dump
2. manage syncdb will take care of producing a almost empty database skeleton
3. the tables auth_permission and djangocontenttype in the database sekelton need to be cleaned completely
4. manage loaddata reads the data from the dump and writes it back into the your new database

Rejoice.
