I doubt that would happen. If there's more than analyze to do after
the upgrade, the file would get a new name, so the "API" would change
anyway.

Well I don't like shell scripts containing rm -rf commands sitting in
the filesystem either.

Another nitpick here: What pg_upgrade outputs doesn't even work on
most systems, you need to ./analyze_new_cluster.sh or "sh
analyze_new_cluster.sh".
