[jdreffein]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet:
• Ruby:
• Distribution:
• Module version:

How to reproduce (e.g Puppet code you use)

take any distribution with configured own repository management or subscription (like via Katello or RHEL satellite).
Set used database for director to postgresql (should be default) and assure required postgresql repos are presented by subscription.

What are you seeing

There are errors showing up while trying mysql and sqlite3 packages.

What behaviour did you expect instead

only include postgresql packages (default) unless other db_driver is configured for module
