Copy the password printed from the above command, and run the following to connect to Postgres using the above password when prompted:
# psql -U cb -h localhost -p 5002
ALTER USER 'user_name' WITH PASSWORD 'new_password';
In the ALTER USER command, replace 'user_name' with the name of the account that was changed (example: cb). Then in the 'new_password' field, put in the original password that you got from the cb.conf command in step 2.
