Enumeration Deferrable

Can be used to make foreign key constraints deferrable. 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.

class MyModel extends Model {}
MyModel.init({
  foreign_id: {
    type: DataTypes.INTEGER,
    references: {
      model: OtherModel,
      key: 'id',
      deferrable: Sequelize.Deferrable.INITIALLY_IMMEDIATE
    }
  }
}, { sequelize });
