Not that I'm aware of.   If you have a backup, you might be able to
recover the missing object from the backup.   Otherwise, if you
know what's referencing the object, you might be able to
use application knowledge to affect a repair.  If you use the -r
option, you get a database of reverse references, which is
very handy for figuring out what's missing.
