Yes, and that's what I'm doing, although it is significantly less  
precise, in that:

* Columns with different types may successfully compare (e.g., NULL  
and '')
* No (easy) way to tell if two records have different numbers of columns

But it's good enough for 8.3 if there is no other workaround.

Thanks,
