The default is determined like this:

       orderBy = table->GetQuotedPrimaryKey();
       if (orderBy.IsEmpty() && hasOids)
            orderBy = wxT("oid");
       if (!orderBy.IsEmpty())
      {
           if (pkAscending)
                orderBy += wxT(" ASC");
           else
              orderBy += wxT(" DESC");
      }

Essentially, we try to follow the ordering in the index.
