fixes formula to comply to its spec

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.
