Postgres with PHP

Hello,

I can´t get my local Postgres database work with PHP over TCP/IP
(Browser) connection.

PHP 3.12 is installed as Apache-module (Apache 1.3.9)
Postgres version 6.5., both came with my SuSE 6.3

The query script is running without problems at my provider´s machine
(apache 1.3.9, PHP 3.0.7 as CGI, Postgres 6.5).

On my local SuSE-box, psql monitor works fine. Access per telnet from
remote host (win98) is ok, there are no error messages or problems
with queries.

The problem occurs when connecting with
$conn = pg_Connect("192.168.0.1", "5432", "username" ,"***",
"name_db");
I get following error message:

Unable to connect to PostgresSQL server: pgReadData() -- backend
closed the channel unexpectedly. This probably means the backend
terminated abnormally before or while processing the request.

Log message:
Usage: /usr/lib/pgsql/bin/postgres [options] [dbname]
-A on enable/disable assert checking
[...]
-v version set protocol version being used by frontend

I searched all manuals and the archive, but I have no ideas.

Thanks,
Catharina
