The different examples are all pretty much just different ways of writing the same thing. And then another different way of writing the same thing is presented, with "db:" prepended. Huh.
The only thing that is substantially different between any of these is the engine/protocol/adapter/whatever section. Perhaps that field should always refer to the protocol type and not the driver, but I consider that problem pretty negligible.
