If you’re trying to set up a robust relational database system on your Debian 12 server, PostgreSQL is a great choice. Known for its stability, performance, and open-source nature, PostgreSQL is widely used by developers, system admins, and enterprises alike. This forum post walks you through the process to install PostgreSQL on Debian 12, based on the reliable and updated instructions from Vultr’s official guide.

 Why Choose PostgreSQL on Debian 12?

Debian 12 (Bookworm) offers strong compatibility with PostgreSQL’s latest versions. Combined, they provide a secure, scalable database setup ideal for web apps, business analytics, or even hobby projects. Installing PostgreSQL on Debian 12 is now simpler than ever using the Vultr documentation as a guide.

Installation Steps Overview (From Vultr Docs)

Below is a simplified walkthrough of the main steps involved in the Vultr guide.

1. Update Your System

Before anything, make sure your Debian 12 system is up to date:

sudo apt update && sudo apt upgrade -y

2. Install PostgreSQL

Run the following command to install PostgreSQL:

sudo apt install postgresql postgresql-contrib -y

This installs the core PostgreSQL engine and some helpful additional tools.

3. Check Service Status

Verify that PostgreSQL is running:

sudo systemctl status postgresql

If it's inactive, use:

sudo systemctl start postgresql

4. Access PostgreSQL Shell

PostgreSQL uses its own user account. Switch to it:

sudo -i -u postgres

psql

Once inside the PostgreSQL prompt, you can begin managing your databases.

Optional: Create New Database and User

To create a new user and database:

CREATE USER myuser WITH PASSWORD 'mypassword';

CREATE DATABASE mydb;

GRANT ALL PRIVILEGES ON DATABASE mydb TO myuser;

Exit with \q.

Tips from Vultr Docs

• The guide also covers how to enable remote access by editing the postgresql.conf and pg_hba.conf files.

• Remember to open the PostgreSQL port (usually 5432) in your firewall settings if you're allowing external connections.

• Always secure your PostgreSQL instance, especially on public servers.
