When using the "winget" command to install PostgreSQL on Windows, the default superuser password is not set during the installation process. Instead, it prompts you to set a password for the superuser (typically named "postgres") during the installation. You will be asked to enter a password for the superuser twice to confirm it.

It's important to remember the password you set for the superuser during installation, as you will need it to perform administrative tasks and access the PostgreSQL database server. If you have forgotten the password or need to reset it, you can follow the steps below:

  1. Stop the PostgreSQL service: Open the Services window (services.msc), find the PostgreSQL service, and stop it. The service name is usually "postgresql-x.x" (where x.x represents the version number).

  2. Open a command prompt as an administrator: Right-click on the Command Prompt shortcut and select "Run as administrator."

  3. Switch to the PostgreSQL bin directory: In the command prompt, navigate to the PostgreSQL bin directory. The default path is typically "C:\Program Files\PostgreSQL\x.x\bin" (where x.x represents the version number).

  4. Run the password reset command: Execute the following command to reset the password for the superuser:

    bash
    postgresql.exe --single -D "C:\Program Files\PostgreSQL\x.x\data" -U postgres

    Replace "x.x" with the actual version number of PostgreSQL.

  5. Enter the new password: You will be prompted to enter a new password for the superuser. Enter the new password twice to confirm it.

  6. Exit the command prompt: Once the password reset is successful, you can close the command prompt.

  7. Start the PostgreSQL service: Open the Services window again, find the PostgreSQL service, and start it.

After completing these steps, you should be able to log in to the PostgreSQL database using the new password you set for the superuser.

Note: If you have installed PostgreSQL using a different method or package manager, the password reset process may vary. The steps mentioned here are specific to a PostgreSQL installation performed using "winget" on Windows.
