/**
* 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
* });
* ```
