Here is the simple solution for installation Postgresql without getting errors(cluster errors and authentication errors),i have followed below steps and i got installed postgresql sucessfully

1. create new user in windows from controlpanel-->user accounts

2. After logged into new user(whic u hve created) copy postrgresql(.exe) application into any directory(other than 'C') and click on the application to install(dont forget to change the installation directory to which u have copied the application file above).

3. after completion of installaion change below configurations in postgresql.conf and pg_hba.cof

add like below in your postgresql.conf

listen_addresses = '*'  

add like below in your pg_hba.cof

host     all     all     127.0.0.1/32    trust
# IPv6 local connections:
host     all     all     ::1/128     trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
# host   sameuser    postgres    127.0.0.1/32    trust
#host    replication     postgres        ::1/128                 md5
