Looks like you are missing the php_pgsql extension (I assume you
are running on a Windows server). On Debian GNU/Linux, it is called
php5-pgsql (or php4-pgsql, as appropriate). Not sure what it would
be called for Windows, but something similar.

Simply enabling it (by uncommenting the line in your php.ini file)
is not sufficient - the actual library needs to be installed as well.

Cheers,

Bob Edwards.

first create a file that contains this

<? phpinfo(); ?>

save this with php extension, run this file from the browser and seek for the directory extension, then look if the
filephp_pgsql.dll is there
