If Elphick's site doesn't have it I doubt you'll find it anywhere else. I think it's kind of unfare that only RPMs are "officially" distributed by the PG Team. But then it might be because nobody every asked the PG team to have an official .deb package.
I don't think it'd be too hard to get the source deb package for 7.1 beta 5 and upgrade it to RC2, then rebuild the package.
