Migrate Database from PostgresSQL (Heroku) to MonogoDB cloud or Firebase

[Rishabh-malhotraa]

Heroku free postgres is really slow and you cant use it outside heroku, as I was panning to make a public API for leetcode questions it is better to either switch to a cloud database provide which is faster and has more storage, currently heroku caps to 10000 entries which is an absolute bummer.
Choose any of the three:-

1. MongoDB Cloud
2. Firebase Storage
3. DynamoDB from aws

MongoDB is preferred if you are choosing a NoSQL DataBase.
