What is wrong ?

Hi,

I have been trying to have PostgreSQL up on the top of cypwin for sometime without succee. After I follow the
instruction on, I get the following error messages:

$ initdb -D /usr/share/postgresql/data
The program
    '/usr/bin/postgres'
needed by initdb does not belong to PostgreSQL version 7.2.1, or
there may be a configuration problem.

This was the error message issued by that program:
/usr/bin/postgres: invalid current euid 500



Can anyone tell me what is missing?

Thanks very much.

v.
