PostgreSQL Exercises
Welcome to PostgreSQL Exercises! This site was born when I noticed that there's a load of material out there to help people learn about SQL, but not a great deal to make it easy to learn by doing. PGExercises provides a series of questions and explanations built on a single, simple dataset.

Looking for PostgreSQL tutorials
From the official PostreSQL website, there is a number of beginner tutorials to check out.
https://www.postgresql.org/docs/online-resources/
Depending on where you think learning SQL will take you (or where you want to go), like doing serious data analysis or data-driven application development for bigger companies. PostgreSQL is a better choice among the free databases than MySQL (in my opinion).
The learning curve for PostreSQL is a little steeper, but is it worth it in the long run. Whereas MySQL is for smaller, simpler projects. MySQL is also now owned by a big face-less corporation and it's future is in some doubt. MariaDB is the open-source fork of MySQL, in case you're interested.
I hope that helps. Good luck!
