To install PostgreSQL on Ubuntu, follow these steps:

  1. Update the package manager index: sudo apt update
  2. Install the PostgreSQL package and any required dependencies: sudo apt install postgresql
  3. Once the installation is complete, you can create a new PostgreSQL database cluster. To do this, run the following command: sudo pg_createcluster 11 main --start
  4. This will create a new PostgreSQL cluster with version 11, using the main configuration. The --start option will start the cluster after it is created.
  5. After the cluster is created, you can connect to the PostgreSQL server as the default postgres user: sudo -u postgres psql
  6. From here, you can create new databases and users, and perform other tasks.


Note: The version number (e.g., 11 in the example above) and the configuration name (e.g., main) can be customized as needed.

  1. Open a terminal and update the package manager's package lists:

2
sudo service postgresql start
sudo systemctl enable postgresql


  1. To verify that PostgreSQL has been installed and is running, connect to the default PostgreSQL server using the psql command-line interface:
1
sudo -u postgres psql


You should see the psql prompt, which indicates that PostgreSQL is running and you are connected to the default server.

  1. To exit the psql prompt, type q and press Enter.


That's it! You have successfully installed and configured PostgreSQL on Ubuntu.
