PHP not loading php_pgsql.dll on Windows

Question

PHP 5.2.8 is refusing to load php_pgsql.dll, with the following error:

Warning: PHP Startup: Unable to load dynamic library \'D:\\PHP\\ext\\

Answer 1

Check out the info on the PHP PostgreSQL installation page: http://us.php.net/manual/en/pgsql.installation.php

On a Windows server, configured with Apache, adding the following line to httpd.conf to load libpq.dll can save you a lot of time :

LoadFile "C:/Program Files/PostgreSQL/8.4/bin/libpq.dll"

Note that you will have to change your folder accordingly to the installation path and version of PostgreSQL you have installed. Also note that having Apache and PostgreSQL on the same server for production environments is not recommended.

This fixed my setup instantly.
