  2. Select "Windows" as your operating system.
  3. Click the installer download link for the latest stable version.
  4. Choose the latest version and the correct architecture (Windows x86-64 for 64-bit systems). Click "Download".
  5. If the download doesn't start automatically, click the "Start the Download Now" link.

Important: Ensure you have an active internet connection and temporarily disable any third-party antivirus software before starting the installation.

  6. Set a password for the PostgreSQL superuser ("postgres"). Click "Next".

Note: pgAdmin 4 is a graphical administration tool for PostgreSQL. It's used to manage databases, execute queries, and perform other administrative tasks. It supports various browsers (Edge 44+, Chrome 72+, Safari 12+, Firefox 65+).

  1. Set a master password for pgAdmin 4.
  2. Connect to the server (PostgreSQL12.3, by default). You'll need the superuser password you set during installation.

Conclusion

With PostgreSQL successfully installed and pgAdmin 4 configured, you're ready to begin working with PostgreSQL databases.
