Maybe that could use rethinking, not sure.
It does need rethinking in the era of VMs and SANs. /var/lib/pgsql/15 is
going to be on a different LUN from /var/lib/pgsql/9.6
You can't hardlink between different file systems.
We'd never hardlink. Eliminates the ability to return to the old system if
something goes wrong.
