I agree, why is this still needed? It can run pg_upgrade in the background.

It needs binaries for both old and new versions for some reason.

When you say "in the background" what are you meaning?

Unless something has radically changed with this last release, then the PostgreSQL database needs to be offline while pg_upgrade is running.
