[$] PostgreSQL reconsiders its process-based model

In the fast-moving open-source world, programs can come and go quickly; atool that has many users today can easily be eclipsed by something betternext week. Even in this environment, though, some programs endure for along time. As an example, consider thePostgreSQL database system, which traces itshistory back to 1986. Making fundamental changes to a large code basewith that much history is never an easy task. As fundamental changes go,moving PostgreSQL away from its process-oriented model is not a small one,but it is one that the project is considering seriously.
