* Fix `opensuse-leap-15` (enable `suse` and workaround `service` bug)
* Use port `5433` for `debian` and `opensuse-leap-15`
* Use upstream repo version `10` for `debian`
The reworks in merge #110 broke this formulas kitchen based specs.
This MR changes a few minor things, mostly pillar.example and other inconsistent documentations.
Also, the use of db_user for `postgres_tablespace.present` and `postgres_database.present` now fits the states options, as db_password etc can be specified as well.
