My vote goes to doing nothing about the token on the back branches.
Just prevent bogus pg_locks output.
Nobody cares about the specifics of the token value -- though perhaps
you foresee a need to have it for testing purposes. I suppose that
adding a column to pg_locks on the master branch is the easy way of
resolving the situation, even if we don't really expect anyone to use
it.
