Postgres doesn't have to be. The storage arrays are getting smarter aswell. Take the NetApp storage array, you can expand, reassign disks to a logical volume, resize a logical volume online. And I'm not sure if it can be done online, but the head (the controller part) should be hotswappable aswell. This way you can upgrade your 1TB netapp to a 6TB netapp.

But if you're using a simpler array, a simple SAN or NAS, it's indeed very pleasant to have the ability available in your database.
