SE-PostgreSQL Specifications

Here is the initial draft of SE-PostgreSQL specifications:
 http://wiki.postgresql.org/wiki/SEPostgreSQL_Draft

I've described it from the scratch again with paying attention
for the people knowing nothing about SELinux.
In some points, it uses comparison between the database privilege
mechanism and SE-PostgreSQL for easy understanding.

Please point out, if ...
- Its composition can be improved.
- Here is not enough introductions for what user wants to know.
- Here is too much explanations, more brief one will be available.
- Here is not easy understandable for database folks.
- Here is not enough English quality.
- And so on...

In addition, I would like to fix its specifications during the discussion.

Thanks,
