Yes, this is the expected behavior; there are several threads about this
on the various mailing lists, here's the first I fond:
https://www.postgresql.org/message-id/CAHJZqBDe1-oiYtdh5pcWLAhr3jsDMFQg4miv3PYADH3YWKqZ2w%40mail.gmail.com
A solution is to override the log statement while setting the password:
BEGIN;
SET LOCAL log_statement = 'none';
ALTER USER ... SET PASSWORD ...;
COMMIT;
Another would be to prepare the digest client-side instead, and use
\password in psql.
