Looking at the javadoc I can't see anything else about integrity
constraints, so I'd have to believe that this is what they mean. It seems
if this was for something above and beyond regular constraints they'd have
something for the base level as well. I think we should return true.

It works for foreign keys which reference a primary key, but does not work
for columns referencing a unique index.
