Weighing the benefit of this proposal against the pain for newbies and old farts to learn yet another way of doing things, and the perceived inconsistency I vote to leave it at status quo.

If we change the way we deal with queries then we should rethink the whole thing and in that case I'd strongly prefer Don's (?) -generic, -oracle, -postgresql style. Until then, I'll happily use Bart's emacs extensions to make my life easier.
