Re: What is a password for?

Yes, I set a password. I'm sure that I used the right password for
'postgres'. I can su to 'postgres' with it.

~ $ createuser -U postgres -W test
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) n
Shall the new role be allowed to create more new roles? (y/n) y
Password: <i input password here>
createuser: could not connect to database postgres: FATAL: password
authentication failed for user "postgres"
