I have not used PostgresSQL but I use Sequelize often. If you can kindly post the error, I can look further, but here are some helpful tips: Make sure PostgresSQL is installed (npm install --save pg@6 pg-hstore) Make sure sequelize-cli is installed (npm install -g sequelize-cli) Test DB without Sequelize (ie command line) Also, see if this article helps => https://codeburst.io/creating-a-dynamic-database-using-postgres-and-sequelize-5264cea5a2d

Hi all, I'm a Sysadmin working for a non-profit. I have decided after decades of Windows Administration, that I would invest in learning Linux and Web Development. I am at the tail end of a class in George Washington University for full stack development -> https://bootcamp.cps.gwu.edu/. The class has taken me from 0 to the 60, and now I would like to push the throttle. I have good background in AWS, Windows Servers, Powershell, etc. The stacks that I would like to master are MERN, MEAN, Meh, anything related to Node.js.

I would recommend the Developer only because it's specific to knowing and understanding the services (and related SDK's) for the different services you can consume. For example, using DynamoDB instead of Mongo, using S3 instead of NFS/Fileshares/Local Storage, using Elastic Beanstalk for easy/automatic deployment of code, and the list goes on. This is the next Cert I'm work on, I currently have the AWS Solutions Architect.
