The fact is, the world seems full of exotic hardware. This pgpolicy was

Yep, I think I requested it for the San Volume Controllers (IBM
standalone ESS derivative (and as I say that no doubt a ESS team member
will flame me ;))
Well, at least it's what I understood from the request :/
One would have thought that group_by_serial was here to cover that
scenario, but that hardware just doesn't work that way.
All the path have the same serial, but the show up from different nodes.
