Attaching/detaching tablespaces (or, in general, parts of a DB) - Mailing list pgsql-general

Is it possible to attach or detach parts of a DB (e.g. tablespaces),
such that I can flexibly move the disks containing the DB tables
around to different hosts?

The last discussion I could find on this topic is from 2007, and the
answer was "No":

Wondering if there's been any change to the answer since then.  I can
alternatively dump/load, which is slower and requires 2x the disk
space.  Thanks in advance.
