If you keep indexes in separate tablespaces from tables a quick worse
case type test would be to sum the allocated bytes of storage in
sys.dba_extents for all table storage tablespaces. (Skipping system,
temp, rbs tablespaces, and index tablespaces). The exp will almost
surely not exceed this and will probably be much less since the Oracle
block overhead in not exported.
