psql: FATAL: Password authentication failed for user "Administrator"

Hi,

I am using postgresql windows based "8.0-beta2-dev3". I have provided default user and password while installing. When i am trying to connecto to psql through dos command prompt, i am getting following error:

[D:\Postgresql\8.0-beta2-dev3\bin]psql
psql: FATAL: Password authentication failed for user "Administrator"

I dont have user named "Administrator", i have only user "postgres" and my "pg_hba.conf" details are:

# TYPE DATABASE USER CIDR-ADDRESS METHOD
local all postgres md5
# IPv4-style local connections:
host all all 127.0.0.1/32 md5
# IPv6-style local connections:
#host all all ::1/128 md5

My question is how to connect postgres through the dos command prompt, to use commands such as pg_dump etc..

thanks,
kuru
