Breaking tab completion in new psql against old servers might be acceptable as it's a fringe feature, but I don't think your recommendation of matching versions is practical. Lots of people manage multiple server versions and using the latest psql for all of them is currently, as far as I know, a perfectly supported way of doing that, getting new psql features and keeping compatibility. I think it would be a pity to loose that.
