This article demonstrates how to install PostgreSQL on a Windows machine with a step-by-step walkthrough. Follow the instructions below and refer to the accompanying images to guide you through the process.

​
Step 1: Locate the PostgreSQL Website

Begin by opening your preferred web browser and searching for “PostgreSQL.” Typically, the PostgreSQL website appears as the first result. Click on the link that directs you to PostgreSQL.org.
The image shows a Google search results page for "Postgres," featuring ads and a knowledge panel with information about PostgreSQL, including its description, release details, and related searches.

​
Step 2: Download the Windows Installer

Once on the PostgreSQL website, locate and click the Downloads button, and then select Windows. At the top of the Windows download page, click the link to download the installer.
The image shows a webpage for downloading PostgreSQL Windows installers, detailing platform support for various PostgreSQL versions. It includes a table listing compatible Windows platforms for each version.
On the download page, you will find a list of available PostgreSQL versions. The latest version is currently 13.4, though you may choose a newer version if available. The installation process remains largely the same across versions. After the download is complete, run the installer. If a User Account Control (UAC) prompt appears, click Yes to proceed.
The image shows a Windows User Account Control prompt asking for permission to allow the app "postgresql-13.4-1-windows-x64.exe" to make changes to the device. The options "Yes" and "No" are available for selection.

​
Step 3: Run the Installer

When the installer opens, click Next on the welcome screen. The default installation directory is pre-selected; most users do not need to modify this path. The installer then presents you with options for the components to install:
  • PostgreSQL Server: The core database engine.
  • PgAdmin: A graphical tool that simplifies managing your PostgreSQL instance. It is recommended to install PgAdmin for easier database administration.
  • Stack Builder: An optional feature that assists in installing extensions and additional tools for PostgreSQL. For basic usage, you can leave this option checked.
  • Command Line Tools: Essential for performing database operations via the command line. It is advisable to retain these tools for future tasks.

Continue through the installer by accepting the default data directory settings.

​
Step 4: Configure the Database

You will now be prompted to establish a password for the superuser account. Make sure to select a secure password and remember it for future use.
Keep your superuser password secure as it is critical for managing your PostgreSQL instance.
Next, you will be asked to specify the port on which PostgreSQL will run. The default port is 5432. While you can change this port, it is recommended to use the default to avoid configuration complications.

Step 5: Complete the Installation

Once the installation is complete, click Finish. To manage your PostgreSQL instance, launch the PgAdmin application. You can locate PgAdmin by searching for it in the Windows start menu.
