I reconsidered the above two options have no differences fundamentally.
In other word, making a new enhanced security implementation based on
requirements also means making a consensus various security mechanism
can have its individual rules including guranuality of access controls.
So, I'll decide to try to implement "fine-grained-only" security
mechanism also, because someone have such a requirememt.
However, its schedule is extremely severe, if is has to be submitted
due to the deadline of CommitFest:Nov.
It is my hope to concentrate development of SE-PostgreSQL in v8.4
development cycle, and I think the above "fine-grained-only" one
should be pushed to v8.5 cycle.
