We can't edit the database until recovery is over, so that doesn't help
us while in recovery mode. So not an option.
It doesn't help us after recovery mode either because there is no
infrastructure (yet) for an index AM's rmgr to exact a transaction after
completion of recovery. So yes, that is the way it will be done, but
there is a non-trivial effort to allow it to happen.
