After unregistering as versioned all objects in a schema the simple relationships still show up as versioned when I check with sql. There is also one feature dataset that has the same problem. When I check the feature dataset with ArcCatalog it gives me the option to register as versioned. So, I think the sql query is not telling the whole story... Why is this happing?
select i.name as name, t.name as type
from sde.gdb_items_vw i
join sde.gdb_itemtypes t
on i.type = t.uuid
where i.definition like '%Versioned>true%'
