/**
 * Can be used to
 * make foreign key constraints deferrable and to set the constaints within a
 * transaction. This is only supported in PostgreSQL.
 *
 * The foreign keys can be configured like this. It will create a foreign key
 * that will check the constraints immediately when the data was inserted.
 *
 * ```js
 * class MyModel extends Model {}
 * MyModel.init({
 *   foreign_id: {
 *     type: Sequelize.INTEGER,
 *     references: {
 *       model: OtherModel,
 *       key: 'id',
 *       deferrable: Sequelize.Deferrable.INITIALLY_IMMEDIATE
 *     }
 *   }
 * }, { sequelize });
 * ```
 *
 * The constraints can be configured in a transaction like this. It will
 * trigger a query once the transaction has been started and set the constraints
 * to be checked at the very end of the transaction.
 *
 * ```js
 * sequelize.transaction({
 *   deferrable: Sequelize.Deferrable.SET_DEFERRED
 * });
 * ```
