sequelize does not support JSONB column as foreign key

I tried to make a JSONB column as a primary key. It’s OK for postgreSQL and normal use of sequelize. But it will get error when use the getXXX associate function.

in model.js

    if (typeof param === 'number' || typeof param === 'string'  || Buffer.isBuffer(param)) {
      options.where = {};
      options.where[this.primaryKeyAttribute] = param;
    } else {
      throw new Error('Argument passed to findById is invalid: '+param);
    }

The if statement should be

    if (typeof param === 'number' || typeof param === 'string'  || typeof param === 'object' || Buffer.isBuffer(param)) {

Feels really dirty to me to use a json column as a primary key - Whats wrong with a regular SERIAL 😃?

It is just a test to use a JSONB column as primary key.
