title: What are common issues with sequelize
body: <p>I've been considering using node/express/sequelize for a project but I've read in a few places where people strongly advise against using sequelize as an ORM. Can someone advise me on the major reasons why people say not to use sequelize? </p>
  
  <p>For clarity, I'm using postgres as a database for relational data, not no-sql</p>
