Yes, if you intentionally send the query in clear text, it will be logged
in clear text.

Just like with your report about creating user, it is clearly documented in
the ALTER ROLE documentation that if you don't want this, you should use
\password or a similar functionality, and not the cleartext ALTER USER.

You can also turn off command line history in psql if you want, by running
it with -n.
