Remarks

I recently started reading the book "High Performance PostgreSQL for Rails" (thanks a lot for the great book! 🥇) and was disappointed to find that I had to spend hours setting up the environment before I could start working on the exercises.

This pull request aims to streamline the setup process, allowing you to get started more quickly. However, please note that I have not tested all features yet, as I have only reached the section where I need to create millions of rows in the database.

This PR is just the first step, from which we could start to improve the setup.
