Hi @andatki,

Happy New Year! Just getting back into the book after a long pause and decided to restart from the beginning.

Postgres.app is available on Homebrew as the cask postgres-unofficial:

❯ brew info --cask postgres-unofficial
==> postgres-unofficial: 2.9.2,13-14-15-16-17-18 (auto_updates)
https://postgresapp.com/

You might simplify the installation instructions a bit by adding it to sh/intro_brew_install_steps.sh.

Thank you!
