Since the ODBC driver seems to be 9.6, it's not surprising that it's
linked to a 9.6 libpq. Can't you update that?

It seems like your server may be set to hash passwords via SCRAM. If you
need compatibility with ancient client versions, you need to make sure
your password is hashed the old way with md5. Observe:
regression=# create user joe;
CREATE ROLE
regression=# set password_encryption to "scram-sha-256";
SET
regression=# alter user joe password 'foo';
ALTER ROLE
regression=# select rolpassword from pg_authid where rolname = 'joe';
rolpassword
