They are separate. If you look at the patches you'll see a pgace part, this is 
where the core interfaces to the security backends, and you'll see a rowacl 
backend and an sepgsql backend.

Personally I'd like to see all of the access control moved out to use pgace, 
including the standard DAC permissions but I doubt that would never happen.
