pg_connect() is not working- urgent

[Anon]

When I was trying to connect to the Postgresql database usint pg_connect, its giving the following error.
"Fatal error: Call to undefined function: pg_connect() in c:\inetpub\wwwroot\php\pgconnect.php on line 4"

What will be the problem?

I am using php4 in iis5.0.

Thanks in advance

How certain are you that your PHP was compiled with
PostgreSQL support enabled? It sounds like it wasn't...
