Wasn't it still basically a university project for researching MVCC at that point? I love universities of course but we must admit they produce interestingly-architected abandonware sometimes.

My sense was that it got a pretty thorough review and revision/rewrite in the transition from Postgres to PostgreSQL.

PostgreSQL has evolved a LOT in the last decade even. I thought the university project was looking at OO paradigms in relational databases (inheritance between relations and the like).

The change from Postgres to PostgreSQL was largely a UI/API change and the move from QUEL to SQL. However, over time virtually all of the software has been reviewed and rewritten. It's an excellent project, and I have been using it since 6.5.......
