I guess it could be a new BuiltinTrancheId for this dsa but not sure what Nathan
and Sami have in mind.

Yes, it will be a BuiltinTrancheId for a shared memory that is allocated 
during postmaster for tracking tranches. The shared memory will then 
only be used by normal backends to register tranches. Any tranche 
registered during postmaster is inherited by the backends.

Sami
