I'd love to, but unfortunately the service consuming the database is
very, very strictly limited to one connection string, which entails one
set of credentials, one server and one database, and more connections
cannot be created as-needed at runtime without restarting the service,
which in our industry is not acceptable.

So, unfortunately I cannot avail myself of such an elegant solution;
instead, I must access all the schemas via one role.
