PostgreSQL Access Control Extension


As I announced alpha version of SE-PostgreSQL about one month ago,I'm working for development of a security facility integrated with secure operating system.
It provides database users fine grained mandatory access control including row and column level one, and integration with operating system security policy.
This concept may have applicability to other secure operating system such as Trusted Solaris. Just after the announcement,'s people were interested in SE-PostgreSQL works, and contacted me.
They also want to implement a similar functionality on their operating system using Trusted Extension (TX).
We got an agreement that a common framework like LSM will be useful to implement and maintain those secure facilities.
I want to have a discussion and get feedbacks about this idea from PostgreSQL developers.
