As I said I don't know how datafiles in oracle are working. All you have on
postgres is tablespaces, default tablespaces and moving relations from one
tablespaces to another.
In general, postgres doesn't try to reimplement solution to problems that are
nicely solved at the operating system level, so if those datafile are
reimplementing something similar to LVM, then no postgres doesn't have
something like that and probably doesn't want it.
