Hi Nick,

from the "Operations Guide"

Error Message:
Validation error on column in table <string>

Causes and Suggested Actions to Take:
The database cannot be restored because it contains data
that violates integrity constraints
. Try deleting constraints from the metadata by specifying
-no_validity during restore
