DBObjectHandle :: DeleteExtent - Delete extent
The function deletes an extent. This is not done automatically when the extent has no instances anymore.
The extent will be removed completely, which includes removing all instances from derived extents. When the extent owns the instances, also the instances will be deleted, which may take some time.
Extents should be removed, before being deleted in the dictionary. When the extent definition is not available anymore, the extent will be deleted without deleting owned instances. This may cause database error, which can be repaired calling CheckDB().
