Forum OpenACS Development: Re: Towards OpenACS 5.9
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.
