For the case of upgrading, it wouldn't work. But there are certainly
other cases where it would help. Say from your central pgadmin console
administering 10 servers from 3 different major release trees :-(
It can be done with commandline pg_dump, but it means you have to have
three different installs on your management or backup or whatever
machine. Those cases would certainly be easier if you could just call a
backup API on the server that would feed you the data... (yes, there are
ways to do it with ssh tunneling and whatever, but that's yet another
external service that has to be set up and configured)
I'm not saying it's worth the work and potential downsides, just that
there are clear upsides :-)
