I looked at the PR (https://github.com/camptocamp/puppet-postfix/pull/50)
to add "Hiera support" and it appears that it just add some parameters that
take hashes that are used to auto-generate instances of defined types. I
wouldn't call this "Hiera support", I'd just call it "convenience
parameters".
There's no reason you couldn't just do this on your own in a profile (or
anywhere else):
$configs = hiera('<key_name>')
create_resources('postfix::config', $configs)
