Learning from other open source databases

Here is a general call for people to review other open-source database
software and report back on things PostgreSQL can learn from them.

I can see Interbase, MySQL, and SAP DB as being three database that
would be worth researching.  I am willing to assist anyone who wants to
give it a try.  I have all the sources here myself.  I even have old
University Ingres, Mariposa, and Postgres 4.2.
