``None`` disables this functionality.
If you use a factory of apps (for example by using
:func:`teal.teal.prefixed_database_factory`) and then set this
value differently per each app (as each app has a separate config)
you effectively create a `multi-tenant app <https://
news.ycombinator.com/item?id=4268792>`_.
Your models by default will be created in this ``SCHEMA``,
unless you set something like::
class User(db.Model):
__table_args__ = {'schema': 'users'}
In which case this will be created in the ``users`` schema.
Schemas are interesting over having multiple databases (i.e. using
flask-sqlalchemy's data binding) because you can have relationships
between them.
Note that this only works with PostgreSQL.
