Its worth than that, you can get a dump that dumps successfully but doesn't restore: http://archives.postgresql.org/message-id/20130507141526.GA6117%40awork2.anarazel.de But that's not really related to snapshots. And not related to the patch. Imo the whole focus on the time between snapshot taking and taking the locks is a misguided and not really the problem.
