No, this is not the case.  su makes you become the user named, root by
default.  Your first su makes you root; the second one makes you
postgres.  This is perfectly OK and the right way to do it.

ALTER USER postgres WITH PASSWORD newpassword;

You need createuser privileges to use CREATE USER or ALTER USER.
