The PostgreSQL client is distributed in the appositely named postgresql-client, so all you need to do is run the following:

For Ubuntu (and Debian-based distributions) thats’s the apt command. Linux systems (unlike macOS) have a package manager built in. You’re now ready to run psql and start connecting. This will symlink all the tools (not just libpq) into the /usr/local/bin directory. There’s a small catch though-libpq won’t install itself in the /usr/local/bin directory. Homebrew’s package for the PostgreSQL client tools is the libpq package. With Homebrew in place, you’ll be able to install numerous applications, usually with the programs available in /usr/local/bin.

We recommend Homebrew as a package manager for macOS. In this PostgreSQL Tip, we’ll look at how you can install just psql on Windows, Linux, and macOS, allowing you to quickly get up and running and connected to your IBM Cloud Databases (ICD) for PostgreSQL service. It’s a reasonable assumption if you’re dealing with users who don’t have access to PostgreSQL in the cloud or on a remote server. Most instructions for installing the PostgreSQL tools assume you want the database installed too. Why install all of PostgreSQL when your database server is up in the cloud, managed as an IBM Cloud Database for PostgreSQL? Install only the necessary tools for a lean, mean PostgreSQL client machine

Postgresql yum install
