- Ensure that PostgreSQL has been installed on your machine. The Windows installers can be downloaded from http://www.postgresql.org/download/windows/
- Assuming WAMP Server is installed on c:\wamp, copy C:\wamp\bin\php\php5.4.3\libpq.dll to C:\wamp\bin\apache\apache2.4.2\bin\libpq.dll
- Also see that the following files exist
- C:\wamp\bin\php\php5.4.3\ext\php_pgsql.dll
- C:\wamp\bin\php\php5.4.3\ext\php_pdo_pgsql.dll
- The above two files are PHP extensions and should be enabled using the WAMP menu or the php.ini file
