Hello and welcome to this article on how to install PostgreSQL on Debian 11. In this guide, we will go through all the steps required in a friendly and easy-to-follow manner.

PostgreSQL 15 is a powerful and reliable open-source object-relational database system that provides an extensive data storage and management feature set. It is highly scalable, allowing users to store and manage large amounts of data while providing robust performance and reliability.

Debian 11, on the other hand, is a powerful, secure, and user-friendly operating system that provides an ideal platform for running PostgreSQL 15. Debian 11 is highly customizable and offers many features that make it easy to deploy, manage, and maintain PostgreSQL 15. PostgreSQL 15 and Debian 11 provide a comprehensive data storage and management solution.

Before we get started, ensure you have root access to your Debian 11 system. This guide assumes that you have a basic understanding of the Linux command line and package management.

Update and upgrade the system.

The first step is to ensure that your system is up to date. Open the terminal and run the following commands:

Syntax: sudo apt update

Syntax: sudo apt upgrade

This will update and upgrade all the installed packages to their latest versions.

Add PostgreSQL repository

By default, Debian 11 ships with PostgreSQL version 13. If you want to install version 15, add the PostgreSQL repository to your system. To do this, run the following command:

Syntax: 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 PostgreSQL repository key

Next, we need to import the PostgreSQL repository key. This will ensure that the packages we install are from a trusted source. Run the following command:

Syntax: wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -

This will download and import the PostgreSQL repository key.

Install PostgreSQL 15

Now that we have added the PostgreSQL repository and imported the key let's install PostgreSQL 15. Run the following command:

Syntax: sudo apt install postgresql-15

This command will install PostgreSQL 15 along with all its dependencies.

Initialize the database cluster.

After installing PostgreSQL, we need to initialize the database cluster. Run the following command:

Syntax: sudo pg_createcluster 15 main --start

This command will create a new PostgreSQL cluster called "main" for version 15 and start the server.

Verify the installation

To verify that PostgreSQL is running, we can use the following command:

Syntax: sudo systemctl status postgresql@15-main

This should output the status of the PostgreSQL server.

Congratulations! You have successfully installed PostgreSQL 15 on your Debian 11 system. You can now start using PostgreSQL and its advanced database management features.
