Well, that depends on what "non-heap layouts" you're thinking of. I think there'd be some further work needed to make efficient IOTs possible, but the patchset gets us a long way to be able to do that in a pluggable fashion. Biggest problem would probably be extending the existing index AMs, for secondary indexes, to point to a key wider than a tid, without loosing too much efficiency. Greetings, Andres Freund
