Postgresql installation-initdb failed

Hi,

Can anybody with good knowledge on Postgresql installation on Windows XP
using Cygwin, please help me. I have installed cygwin, run

cygserver-config

both cygserver and postmaster are running as per the messages below. And no
changes have been made to postgresql.conf or any configuration files, and i
am including the version of postgresql below.

 Thanks in advance,
 ajit
