I'm not convinced about this objection - having samples gives a bit of a
heads up on *what* knobs you should at least look at changing.

Also it might be helpful on the -general or -perf lists to be able to
say "try config 3 (or whatever we call 'em) and see what changes..."

I've certainly found the sample config files supplied with that database
whose name begins with 'M' a useful *start* when I want something better
than default...
