Installation problem / cygwin/postgresql/windows

Hi,
I am new in cygwin and postgresql.
Could you please advice how to solve the following problem?

I follow the instructions presented in *
http://www.postgresql.org/docs/faqs.FAQ_CYGWIN.html*<http://www.postgresql.org/docs/faqs.FAQ_CYGWIN.html>

During the installation I have a problem with initdb -D -W -E LATIN1
The /usr/local/pgsql/data is created but by the end of process it is removed

SERVER SIDE:

Your group name is currently "mkgroup_l_d". This indicates that not
all domain users and groups are listed in the /etc/passwd and
/etc/group files.
See the man pages for mkpasswd and mkgroup then, for example, run
mkpasswd -l -d > /etc/passwd
mkgroup -l -d > /etc/group

This message is only displayed once (unless you recreate /etc/group)
and can be safely ignored.

The files belonging to this database system will be owned by user "tsahbaz".
This user must also own the server process.

The database cluster will be initialized with locale C.
