Compiling a PostgreSQL 7.3.2 project with Eclipse

First, I want to apologize if this is a topic for one of the other mailing lists (or completely inappropriate for PostgreSQL mailing lists), but I looked them over, and this one seemed most appropriate.

I am working on a project based on TelegraphCQ 2.1 Data Stream Management System which is in turn based on PostgreSQL 7.3.2. I've decided to use Eclipse. I have managed to import source into Eclipse and to run it, using instructions given here: http://wiki.postgresql.org/wiki/Working_with_Eclipse.

However, where I compile and run the project, in the Eclipse console I get:

POSTGRES backend interactive interface

$Revision: 1.115 $ $Date: 2006/02/06 01:19:46 $

I don't know what to do with this backend interface. I would like to get a postmaster running and to connect to a data base with psql. However, when i try to start psql, it says that there is no postmaster running.

Can someone please give me a hand,

K.K.
