Well, what you're supposed to do is

postgres=# create user dummy_user;
postgres=# \password dummy_user
Enter new password:
Enter it again:
postgres=#

which will result in sending something like

ALTER USER dummy_user PASSWORD 'md5c5e9567bc40082671d02c654260e0e09'

You can additionally protect that by wrapping it into one transaction
(if you have a setup where the momentary existence of the role without a
password would be problematic) and/or shutting off logging beforehand.
