I've also seen a writeup of someone who used clocks. The write is transaction 1234, so the client has to read from a replica that is caught up to 1234 in the WAL, or get bounced to another that does.
And of course there's the Phoenix LiveView solution where the write contains the new data, gets injected back into the page that contained the edit link. That doesn't quite cover the save-reload loop that some users with well-earned trust issues follow.
