psql is the standard command-line interface for interacting with a PostgreSQL. This article will explain how to install psql(Postgres) on various platforms.

Before you begin

Before you begin, make sure that you don't already have psql installed. If you've ever installed Postgres earlier, you likely already have psql installed.

Install Postgres on macOS using Homebrew

Firstly, we need to install the Brew Package Manager. You can ignore this if you already have Brew Package Manager installed.

/bin/bash -c "$(curl -fsSL"

brew doctor
brew update
brew install postgresql
