sequelize update record primary key value

Question

I'm trying to update the id value of an existing instance using Sequelize but it is not being persisted to the DB

// model definition
var User = sequelize.define('users', {
  id: {
    type: DataTypes.STRING,
    unique: true,
    primaryKey: true,
    field: 'id'
  }
)};

// usage
User.findById(oldId).then(function(user) {
 user.id = 'new value';
 user.save(); // Id remains the same in DB
});

I'm using sequelize 3.14.0 with node and a PostgreSQL database.

As others have hinted in the comments, sequelize won't let you update the primary key, see https://github.com/sequelize/sequelize/blob/f482790b85ef2336bb97893c0eaa127d9d6bbc77/lib/instance.js#L334-L336
