PostgreSQL is available in all Ubuntu versions by default. However, Ubuntu "snapshots" a specific version of PostgreSQL that is then supported throughout the lifetime of that Ubuntu version. Other versions of PostgreSQL are available through the PostgreSQL apt repository.
If the version included in your version of Ubuntu is not the one you want, you can use the PostgreSQL Apt Repository. This repository will integrate with your normal systems and patch management, and provide automatic updates for all supported versions of PostgreSQL throughout the support lifetime of PostgreSQL.
The PostgreSQL Apt Repository supports the current LTS versions of Ubuntu:
To use the apt repository, follow these steps:
# Create the file repository configuration: 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 repository signing key: wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add - # Update the package lists: sudo apt-get update # Install the latest version of PostgreSQL. # If you want a specific version, use 'postgresql-12' or similar instead of 'postgresql': sudo apt-get -y install postgresql
Ubuntu includes PostgreSQL by default. To install PostgreSQL on Ubuntu, use the apt-get (or other apt-driving) command:
apt-get install postgresql-12
