What approach are you taking?

It looks like the snapshot builder actually does most of the work we
need for this already, maintaining a stack of snapshots we can use. It
might be as simple as invalidating the relcache/syscache when we exit
(and enter?) decoding of a prepared 2pc xact, since it violates the
usual assumption of logical decoding that we decode things strictly in
commit-time order.
