   If tablespace rstored from granular backup is older that the rest, it can 
have records 
versions created by rollbacked transactions, but in new TIP this transaction 
can be 
already sweeped and its state changed to "committed". Such versions will be 
resurrected.
   If reusing of records formats is implemented, records' layout in outdated 
tablespace 
will not match format with the same number.
   The same problems if a tablespace is newer that the rest.
