Can not connect to the database

This is my first time sending a message.

Here is my problem: I have installed a program, but I can not connect to the
database. This program uses Postgresql, PHP, and Apache.

Here are my server set ups:

Server API Apache ：　Apache Version Apache/1.3.22
Red Hat Linux release 7.2 (Enigma)　：　Kernel 2.2.19-6.2.1ensim-3.1.0-8 on
an i686
PHP Version 4.2.2

The program is in Japanese.

I am not sure this is enough information to give in order to get help. But
this is what I have.

Can anyone help me to solve this problem?

Thanks.
