This updates the module to be able to use puppetlabs-postgresql.
Since this change is a major change, it marks this patch as a breaking change.
I have prepared a suitable amount of upgrade notes for upgrading to this later
version of the module plus removed anything marked deprecated.
As cleanup, I've removed the troublesome 'tests' directory in favour of good
README.md documentation. I've also removed any puppet docs from each module
until such times as puppet docs become automated through the forge. This is
just to avoid contributors having to double their efforts - the README.md
is the authority now.
