- Use standard SQLAlchemy types for the ``id``, ``name``, and ``quote`` columns
- Use ``nullable=False`` to define a ``NOT NULL`` constraint
- Disable indexing of the ``name`` column using ``crate_index=False``
- Disable the columnstore of the ``even_more_details`` column using ``crate_columnstore=False``
- Define a computed column ``name_normalized`` (based on ``name``) that
translates into a generated column
- Use the `Object`_ extension type for the ``details`` column
