Description: ====================================
        Redshift database backend for Django
        ====================================
        
        This product is tested with:
        
        * python-2.7, 3.4, 3.5
        * django-1.7, 1.8, 1.9
        
        
        Differences from postgres_psycopg2 backend
        ==========================================
        
        Type mapping:
        
        * 'integer identity(1, 1)' for AutoField
        * 'timestamp' for DateTimeField
        * 'varchar(max)' for TextField
        * Possibility to multiply VARCHAR length to support utf-8 string, using
          `REDSHIFT_VARCHAR_LENGTH_MULTIPLIER` setting.
        
        Stop using:
        
        * RETURNING.
        * SELECT FOR UPDATE
        * SET TIME ZONE
        * SET CONSTRAINTS
        * INDEX
        * DEFERRABLE INITIALLY DEFERRED
        * CONSTRAINT
        * DROP DEFAULT
        
        To support migration:
        
        * To add column to existent table on Redshift, column must be nullable
        * To support modify column, add new column -> data migration -> drop old column -> rename
        
        Please note that the migration support for redshift is not perfect yet.
