PostgreSQL is a powerful, free, open-source relational database management software. It is very popular due to its reliability, stability, and support for open technical standards. It is versatile and expandable so that you can use it in various specialized use cases with a powerful extension ecosystem. If you want to create highly scalable computing environments in your organization, then PostgreSQL is the best option.

This guide will show you how to install and use the PostgreSQL server on Fedora.

Step 1 – Enable PostgreSQL Repo

By default, Fedora provides a PostgreSQL version 13 via its default repo, so you must enable the PostgreSQL 14 repo in your server.

First, reset the default PostgreSQL repo with the following command.

dnf update -y
dnf module reset postgresql -y

Next, enable the PostgreSQL 14 repo with the following command.

dnf module enable postgresql:14

You will see the following output.

Step 2 – Install PostgreSQL 14

Now, run the following command to install PostgreSQL 14 on your server.

dnf install postgresql-server postgresql

After the installation, initialize the PostgreSQL database with the following command.

postgresql-setup --initdb

You will get the following output.

 * Initializing database in '/var/lib/pgsql/data'
 * Initialized, logs are in /var/lib/pgsql/initdb_postgresql.log

Step 3 – Start PostgreSQL Service

Now, start the PostgreSQL service and enable it to start at system reboot with the following command.

systemctl enable --now postgresql

You can now check the status of PostgreSQL with the following command.

systemctl status postgresql

You will get the following output.

     Loaded: loaded (/usr/lib/systemd/system/postgresql.service; enabled; vendor preset: disabled)

May 07 04:16:16 fedora systemd[1]: Starting PostgreSQL database server...

You can check the PostgreSQL version with the following command.

postgres --version


postgres (PostgreSQL) 14.1

By default, PostgreSQL runs on port 5432. You can check it with the following command.

ss -antpl | grep -i postmaster


LISTEN 0      244*    users:(("postmaster",pid=17975,fd=7))    
LISTEN 0      244            [::1]:5432         [::]:*    users:(("postmaster",pid=17975,fd=6))

Step 4 – Configure PostgreSQL for Remote Access

By default, PostgreSQL is accessible only from the local system. You can allow remote access by editing the PostgreSQL configuration file.

nano /var/lib/pgsql/data/postgresql.conf

Change the following line:

listen_addresses = '*'

Save and close the file, then edit another configuration file.

nano /var/lib/pgsql/data/pg_hba.conf

Find the following lines:

# IPv4 local connections:
host    all             all               ident
# IPv6 local connections:
host    all             all             ::1/128                 ident

Replace them with the next line:

# Accept from anywhere
host all all md5

Save and close the file, then restart the PostgreSQL service to reload the changes.

systemctl restart postgresql

Step 5 – Set PostgreSQL Password

By default, no password is assigned to the Postgres user. For security reasons, setting a strong password for the Postgres user is a good idea.

First, log in to PostgreSQL with the following command.

su - postgres

Once logged in, set a password for the Postgres user.

psql -c "alter user postgres with password 'securepassword'"

Finally, exit from the Postgres Shell with the following command.
