That sounds sufficiently good.  I pushed this patch, after fixing a few
smallish problems, such as an assertion failure because of the
terminating \n in the error message when "postgres --single" fails
(which I tested by introducing a typo in the command).  I also removed
the short option, because I doubt that this option is useful enough to
warrant using up such an important shorthand (Maybe if it had been
-\ or -% or -& I would have let it through, since I doubt anybody would
have wanted to use those for anything else).  But if somebody disagrees,
they can send a patch to restore it, and we can then discuss the merits
of individual chars to use.

I also added quotes to DEVNULL, because we do that everywhere.  Maybe
there exists a system somewhere that requires this ... !!??

Finally, I split out the command in the error message in case it fails.

Thanks.
