What would be the best place for me to look to come up to speed on your use case? (I'm relatively sure that the issue isn't that there's no information to find, but that a sequential pass over all available information would take a *long* time.) I've been working through the issues on WAL-based replicas, and have some additional ideas and alternatives, but I'd like to see the "big picture", including trigger-based replication, before posting. -Kevin
