For security reasons service-accounts are commonly
password-less, and the account disabled.  Usually one
achieves that with a
passwd -l <account>
That way only root is able to switch to that user if
it is (for some reason) required.

That means that the bash you're running is not a login-shell.
Try "su - postgres" instead of "su postgres"
