Let's Solve 42 PostgreSQL Exercises: Introduction

As a fan of the free PostgreSQL Exercises website, I've decided to share the solutions to its most important problems with extensive explanations on how to approach them. I have used this website to teach myself SQL and get a data engineering job without relevant degrees. I believe you can benefit from it too!
This playlist covers all the exercises in the sections: Basic, Joins and Subqueries, and Aggregates.
