Setup postgres

This is the manual way to set up postgres for a test server, for production it is recommended to use a managed database instead.

Either follow these instructions or just run these commands:

# Create the file repository configuration
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

# Import the repository signing key
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -

# Update the package lists
sudo apt-get update

# Install the latest version of PostgreSQL.
# If you want a specific version, use 'postgresql-12' or similar instead of 'postgresql':
sudo apt-get -y install postgresql-15

Then, connect to the database (sudo -u postgres psql) and create the necessary user/database:

CREATE DATABASE server_db;
\c server_db;
CREATE EXTENSION IF NOT EXISTS CITEXT;
ALTER DATABASE server_db SET statement_timeout = '60s';
ALTER DATABASE server_db SET idle_in_transaction_session_timeout TO '5min';
CREATE USER db_user WITH SUPERUSER PASSWORD 'useYourOwnPasswordInstead';
GRANT ALL PRIVILEGES ON DATABASE "server_db" to db_user;

Test the connection to the new database with the custom user: psql -h 127.0.0.1 -U db_user server_db

That's it!
