In order to do that, you would basically need to:
1) Switch password_encryption to 'scram-sha-256' in the server
configuration.
2) Issue an ALTER ROLE command to update the password (likely it is
better to use \password from psql as this would send a hashed password
to the server, which relies on the server setting for
password_encryption).
3) Make sure that pg_hba.conf is using properly scram-sha-256 where it
should as authentication method.

If you do not want to upgrade to SCRAM, it is of course possible to
still remain with md5.
