Thanks, pushed a slightly tweaked version. If you can please verify
that I didn't break anything, it'd be great.

FWIW I think the mode that generated the most connections is -jN --all
--analyze-in-stages. For additional annoyance, one sets up the
"postgres" database with trust auth and others with md5. All the cases
I tried only get a single prompt now.

Thanks Eric for reporting the problem and Haribabu and Michael for
patching.
