However, using invalid or unauthorized sources for packages can lead to implementing untested, defective, or malicious software. Rationale: Being open-source, PostgreSQL packages are widely available across the internet through package aggregators and providers.

Your chosen PostgreSQL vendor may offer its own software repositories as well. For PostgreSQL, the canonical repositories are the official PostgreSQL YUM repository () and the official PostgreSQL APT repository ().

When obtaining and installing software packages (typically via dnf or apt), it's imperative that packages are sourced only from valid and authorized repositories. Contribution modules are optional depending upon one's architectural requirements (they are recommended though). Package installation should include both the server and client packages.

The installation process includes installing the binaries and the means to generate a data cluster. Information Standard Linux distributions, although possessing the requisite packages, often do not have PostgreSQL pre-installed.
