                port: 5432,
                dialect: 'postgres',
                protocol: 'postgres',
                logging: true,
                omitNull: true,
});

var iteration = sequelize.define('iteration', {
               id: { type: Sequelize.BIGINT ,
        primaryKey: true,
        autoIncrement: true,
        unique: true},
    imported: { type: Sequelize.DATE, defaultValue: Sequelize.NOW },
    }, {
tableName: 'iterations'}
);

iteration.create({ imported: Sequelize.NOW}).success(function(iter) {
console.log(iter);
});

You must call sequelize.close() in order to stop the execution. As long as the connection is open the execution does not stop.
