Postgres 14 on Ubuntu 22.04 LTS

by R. S. Doiel, 2022-08-26

This is just a quick set of notes for working with Postgres 14 on an Ubuntu 22.04 LTS machine. The goal is to setup Postgres 14 and have it available for personal work under a user account (e.g. jane.doe).

Assumptions

• include jane.doe is in the sudo group
• jane.doe is the one logged in and installing Postgres for machine wide use
• jane.doe will want to work with her own database by default

Steps

1. Install Postgres
2. Confirm installation
3. Add jane.doe user providing access

Below is the commands I typed to run to complete the three steps.

sudo apt install postgresql postgresql-contrib
sudo -u createuser --interactive
jane.doe
y

What we've accomplished is installing Postgres, we've create a user in Postgres DB environment called "jane.doe" and given "jane.doe" superuser permissions, i.e. the permissions to manage Postgres databases.

At this point we have a jane.doe Postgres admin user. This means we can run the psql shell from the Jane Doe account to do any database manager tasks. To confirm I want to list the databases available

psql
SELECT datname FROM pg_database;
\quit
