apache 2.2.x configuration

add next line apache 2.2.x httpd.conf configuration:

loadfile "c:/program files/postgresql/{version}/bin/libpq.dll"

above line must entered before next line.

loadmodule php5_module "c:/wamp/bin/php/php5.2.11/php5apache2_2.dll"

enable next 2 lines in php.ini configuration file. 'enable' mean, remove trailing ; (semicolon). these, un-comment line.

extension=php_pdo_pgsql.dll extension=php_pgsql.dll

restart wamp

test adding in index.php
