Upgrade 2.0.2/3.15.3 -> 2.1.2/3.16.0 - db:migrate fails loading evr extension when using external PostgreSQL database for Foreman and Candlepin

I guess the safest way forward is to migrate the database back to the Foreman server. Then environment isn’t that big. The remote database just had the convenience of being taken care of and backed up without me having to do anything speciel.

With 2.1 you should be able to have everything external and it’s supposed to be a supported scenario.

Perhaps @katello can take a look at how this should be documented, because I agree that should be done.
