Troubleshooting PHP_pgsql.dll not loading on Windows

If you are encountering an issue with the PHP_pgsql.dll not loading on Windows, there are a few steps you can take to troubleshoot the problem.

Step 1: Check PHP Configuration

Make sure that the PHP_pgsql.dll extension is enabled in your PHP configuration file (php.ini). Look for a line that reads:

extension=php_pgsql.dll

If this line is commented out with a semicolon (;), remove the semicolon to enable the extension. If the line is not present, add it to the file.

Step 2: Check PHP_pgsql.dll File Location

Ensure that the PHP_pgsql.dll file is located in the correct directory. By default, it should be in the ext folder of your PHP installation directory.

Step 3: Check PHP Version and Architecture

Verify that you have the correct version and architecture (32-bit or 64-bit) of PHP_pgsql.dll for your PHP installation. If you are running a 64-bit version of PHP, make sure that you are using the 64-bit version of the extension.

Step 4: Check PostgreSQL Installation

Ensure that PostgreSQL is installed and configured correctly on your Windows machine. The PHP_pgsql.dll extension requires the PostgreSQL client libraries to function properly. Make sure that the libraries are installed and available in your system's PATH environment variable.

By following these steps, you should be able to resolve the issue of the PHP_pgsql.dll not loading on Windows.
