Kindlycheck the attached patch for the changes.

Thanks Ahustosh, yeah I have observed the same, earlier we were
directly copying the whole directory so this was not an issue, now if
some tables of the database are already in the destination tablespace
then we should skip them while copying. I will review your patch and
merge into the main patch.
