> Getting rid of tree_sortkey is the right thing to do, even though I wrote most of the code and came up with the datamodel design and key representation. It was before recursive queries, of course, and we always used "connect by" in Oracle.

I'm not using Oracle with OpenACS anymore and, for the record, I have used recursive queries in PostgreSQL already (in a different context) and found them to be quite handy. That said, I think the tree_sortkey implementation is interesting as a concept as it implies different architectural/design constraints on the system itself i.e. to some extent it does not rely on the underlying RDBMS. Either way, keeping it or not, it would not make much of a difference for me.
