When your editor was in Tokyo recently, he had the privilege to talk with KaiGai Kohei at some length about the SE-PgSQL patch set. This work, developed by KaiGai for the last two years or so, integrates SELinux with the PostgreSQL database manager, enabling fine-grained control over access to data stored within a database. The SE-PgSQL patch has struggled to get into the PostgreSQL mainline; it is now preparing for what may well be its last push to be merged. Whether it's successful may, in the end, depend on whether it receives support from potential users.
