When using command: "createuser --createdb --username postgres --no-createrole --pwprompt openpg" I am getting the following error:

createuser: could not connect to database postgres: FATAL: no pg_hba.conf entry for host "::1", user "postgres", database "postgres", SSL off

PostgreSQL is installed on local machine Windows 7 and I am trying to command on the same local machine

Here is my pg_hba.conf:

# IPv4 local connections:
host all all md5
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#host replication postgres md5
#host replication postgres ::1/128 md5

Could anyone help? Thanks very much.
