I'd really like us to adopt a "default" policy on this. I think it's a waste
to spend time every few years arguing what exact versions to drop. I'd much
rather say that, unless there are concrete reasons to deviate from that, we
provide pg_dump compatibility for 5+3 releases, pg_upgrade for 5+1, and psql
for 5 releases or something like that.
It's fine to not actually spend the time to excise support for old versions
every release if not useful, but we should be able to "just do it" whenever
version compat is a meaningful hindrance.
