Problem: When attempting to access phpPgAdmin through cPanel on premium hosting, you receive a "Login Failed" error message.

Root Cause: The cPanel-integrated phpPgAdmin automatically attempts to authenticate using your generic cPanel credentials. However, these credentials don't match your PostgreSQL database user credentials, causing the login to fail.

Solution: Install a standalone version of phpPgAdmin with these steps:

1. Download phpPgAdmin
   Get the latest release from: https://github.com/phppgadmin/phppgadmin/releases
2. Extract the files
   Unzip the downloaded archive to your local computer
3. Upload to your hosting
   Transfer all extracted files to a dedicated folder on your hosting account (e.g., /phppgadmin)
4. Access the interface
   Navigate to your installation URL: https://yourdomain.com/phppgadmin
5. Log in with database credentials
   Use your actual PostgreSQL database username and password (not your cPanel credentials)

This standalone installation bypasses the cPanel authentication issue and allows you to connect directly to your PostgreSQL database with the correct credentials
