How To Install PostgreSQL on Manjaro 20

In this tutorial, we will show you how to install PostgreSQL on Manjaro 20. For those of you who didn’t know, PostgreSQL is a relational database management system that provides an implementation of the SQL querying language. It’s standards-compliant and has many advanced features like reliable transactions and concurrency without reading locks.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of PostgreSQL on a Manjaro 20 (Nibia).

Prerequisites

• A server running one of the following operating systems: Manjaro 20.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install PostgreSQL on Manjaro 20 Nibia

Step 1. Before running the tutorial below, make sure that our system is up to date:

sudo pacman -Syu
sudo pacman -S git

Step 2. Installing PostgreSQL on Manjaro 20.

Now we run the following command below to install PostgreSQL:

sudo pacman -S postgresql postgis

After the installation finishes, continue with the following command:

sudo su postgres -l # or sudo -u postgres -i
initdb --locale $LANG -E UTF8 -D '/var/lib/postgres/data/'
exit

By default, the PostgreSQL service is started automatically after the installation. You can confirm if it is running with the command:

sudo systemctl status postgresql

You can check PostgreSQL’s version with:

psql --version

Step 3. Installing PgAdmin on Manjaro.

PgAdmin is a web-based PostgreSQL management console. Now run the following command to install PgAdmin on the Manjaro system:

sudo pacman -Sy pgadmin4

Step 4. Accessing the PostgreSQL command prompt.

Once installing the PostgreSQL database server, by default, it creates a user ‘postgres’ with role ‘postgres’. It also creates a system account with the same name ‘postgres’. So to connect to the Postgres server, log in to your system as a user of Postgres and connect database:

su - postgres
psql

Create a new user and database:

### For example, let us create a new user called “meilana” with password “maria”, and database called “meilanadb”. ###
sudo -u postgres createuser -D -A -P meilana
sudo -u postgres createdb -O maria meilanadb

Congratulations! You have successfully installed PostgreSQL. Thanks for using this tutorial for installing the latest version of PostgreSQL on the Manjaro system. For additional help or useful information, we recommend you check the official PostgreSQL website.
