Problems with pg_connect

[nostradamus]

I tried to connect to a postgreSQL Database on my local host.
I used the following Syntax:

$conn =pg_Connect ("host=localhost port=5432 dbname=dbtest");

I got the following error message:

Fatal error: Call to undefined function: pg_connect() in c:\Programme\Apache Group\Apache\htdocs\posttest.php on line 6

I run php on Apache and the postgreSQL database on a cygwin, both on win98.
I cann connect to the db with pgadmin.
What did I do wrong?

You don't have PHP module for Apache compiled with postgreSQL support.

I do not know how to do it on Win, I know only how to do it on Linux. Sorry.
