If you are writing or maintaining a third-party database backend for Django,
you will need to provide a ``SchemaEditor`` implementation in order to work with
1.7's migration functionality - however, as long as your database is relatively
standard in its use of SQL and relational design, you should be able to
subclass one of the built-in Django ``SchemaEditor`` classes and tweak the
syntax a little. Also note that there are a few new database features that
migrations will look for: ``can_rollback_ddl``
and ``supports_combined_alters`` are the most important.
