This is your periodic reminder that we have ~50 applications sharing the 
same database and not only do none of them know how the deployer will 
configure the database, most will not even have an idea which set of 
assumptions the other ~49 are making about how the deployer will 
configure the database.

(Ditto for RabbitMQ.)
