This seems like it would conflict with the proposal from
http://postgr.es/m/CA+TgmoaD8wMN6i1mmuo+4ZNeGE3Hd57ys8uV8UZm7cneqy3W2g@mail.gmail.com
which I still hope to advance in some form at an appropriate time.
It may be weakly related to the current discussion, but I'd like to note that the other proposed patch for making XID's 64-bit [1] will store per-page-common xid data in the heap page special area. It doesn't contradict storing a nonce in this area also, but I'd appreciate it if we could avoid changing heap page special layout twice.
