Installing postgresql-PostgreSQL server

Let's install "postgresql" so that we can use the PostgreSQL database server. PostgreSQL is a convenient relational database system. Use the apt command.

sudo apt install -y postgresql

Confirm that the PostgreSQL database server is installed

Use the status of the systemctl command to confirm that the PostgreSQL database server has been installed.

systemctl status postgresql

The status is displayed as follows.
