Recent versions have

  --no-tablespaces            do not dump tablespace assignments

However, this is really just cosmetic, as the dump is set up like this:

SET default_tablespace = whatever;
CREATE TABLE whichever(...);

If tablespace 'whatever' doesn't exist, you'll get an error on the SET
but the CREATE will succeed anyway.  (I guess this only works cleanly
if the destination machine has *none* of the source's tablespaces,
else things might get assigned to unexpected tablespaces.  But it's
definitely possible to restore a dump without having the same
tablespaces.)
