You're passing a single array into postgresql_password() when it expects
two string arguments in your first example. Try removing the right angle
brackets that are fencing your two hiera calls.
postgresql::server::role { [hiera(my::db::user)]:
password_hash => postgresql_password(hiera(my::db::user),
hiera(my::db::pass)),
}
