So you create some tablespaces by hand. Big deal. This objection is
not strong enough to justify an ugly, klugy definition for where tables
get created.
If tablespaces had to be associated with physically distinct devices
then there would be merit in your concerns, but they are only
directories and so there is no reason that you cannot create the same
set of tablespace names on your new machine that you had on your old.
