Add Marcello Barnaba to the contributor list.

Marcello has come up with a number of elegant solutions when porting
this module to SuSE. Whilst I've not used his commit directly, seeing

Do not start or manage the Postgresql daemon.

In some situations, for example, a clustered environment when and how to
start Postgresql might be taken by another service or system.

If you specify 'manage_service' to be false, a policy-rc.d(8) shell
script is installed that will prevent the Debian / Ubuntu service from
starting at install time.

Additionally the entire service definition is removed, so that other
things can not trigger the service to run (or stop) unexpectedly.
