chown 'postgres': invalid user (win2000 install) - Mailing list pgsql-novice

Hi all

Am trying to install Postgres on a win2000 machine.  Am new to postgres, unix.

I am following the instractions at
:http://www.ejip.net/faq/postgresql-7.1.3.README for a NT services
installation. (cygwin is already installed ofcourse).

followed all the steps, but at step 6
6.
Change ownership of the PostgreSQL data directory: # chown postgres
/usr/share/postgresql/data

I'm getting the following error :
chown 'postgres': invalid user

Any help ?????

thanks

Ben
