pg_close -1 displayed with Win32 binaries

Hello, I've got a little problem - which I frankly don't get. When using the win32 binaries for PHP (yeah - i know - unix is better) and do a pg_close on a postgres database, it always displays the following in the output, even before any headers are sent: pg_close -1 followed by the headers. e.g.: pg_close -1 X-Powered-By: PHP/4.0.5 Pragma: no-cache Expires: Mon, 26 Jul 1997 05:00:00 GMT Last-Modified: Thu, 17 May 2001 10:05:45 GMT Cache-Control: no-cache, must-revalidate Content-type: text/html .. Any ideas how to get rid of this? Thanks, DevilKin
