It may be that you never set that password.
Try "grep postgresql /etc/shadow" as root user.
If the second field is "!!", there is no password set.
You can either become root first, then you need no password
for "su postgresql", or you have to set a password.
You can change the password as user root with
"passwd postgresql".
