PostgreSQL Installation

Projected Time

15 minutes

Objectives

Participants will be able to:

• Use PostgreSQL from the command line (psql) and, optionally, a GUI admin app

Install PostgreSQL on Mac

• Follow the Postgres Homebrew Instructions
• This creates a superuser named postgres
• If you run psql with no args, it assumes you want to connect as your current user (whoami command output)
• Run psql postgres to connect as the superuser
• create database <YOUR_USERNAME>
• \q to quit
• Now you can connect with just psql

Configuration

Being a database, Postgres stores most of its settings in itself! So the config file isn't really useful for us.

Postico GUI App

Install: https://eggerapps.at/postico/

If you created a DB of your user, it should work out of the box if you specify localhost to connect.

PGAdmin GUI App

This is not recommended because it is too advanced and difficult to connect.

Problems

Passwords? with the default setup you shouldn't need a password.
