(PDB-1657) Manage Postgres repos by default

This commit moves to managing the Postgres repos by default. The
reason for this is so that the `puppetdb` class will "just work" by
default on most systems, because PostgreSQL 9.4 is not installed on 6/7
of the distros we support we need to manage the repos so we can install
the latest version.
