php_pgsql.dll on vista

i try install php and apache 2.2 in my vista, and i got some error if i use
php_pgsql.dll, the error is:
PHP Warning:  PHP Startup: Unable to load dynamic library
'c:/php/ext/php_pgsql.dll' - %1 is not a valid Win32 application.\r\n in
Unknown on line 0

and this is the solution. That dll in your package (php-5.2.6-Win32.zip) ,
contain php_pgsql.dll that not support on vista. You can download the dll
that support on vista at:
http://files.dll-vista.com/dllvista-php_pgsql.dll.zip

Sorry for my poor english.
