Re: Recent status of SE-PostgreSQL

Casey,

The problem is you just stuck to one part of the argument and do not see 
the broad picture,

I never claimed anything ( here at least ), I just asked what is the 
practical purpose of SE-PostgreSQL and it had one line answer,

"creating trusted DBMS daemon",   and I see that

and of course nobody claims that the SE-PostgreSQL is a done project

so one has to wait until SE-PostgreSQL reaches the point,

I told it is possible to put databases on separate systems by 
classification, NOT SUCH a BIG DEAL, (while maintaining other forms of 
security measure including filesystem encryption and etc.)
THIS IS ACTUALLY BEING UTILIZED as I'm aware of

and there are Trusted Daemons nobody says there is  no trusted daemon,
The point is right now I think PostgreSQL is not qualified as a trusted 
daemon

but even right now you can use something like that in isolation, without 
combining classifications

SO THIS IS MY QUESTION NOW:
I would be very glad if anybody provides any documentation that 
PostgreSQL is currently treated as trusted daemon,

and thanks for your recommendation,

With all due respect to everybody especially KaiGai,

Let me clear that out, there is no objection of any kind on development 
of something, but what you claimed are not available at Postgres right 
now, and there are so many missing parts not just access control, and 
the point that it is being acceptable as trusted system is just a goal



Best Regards,


Patrick K.
