      Description

      When merging two relsets, we have two preferences:
      1. Merge parent relset into child relset
      2. Merge newer relset into older relset
      Currently, when the two relsets are parent set of each other, we randomly pick a merge order without checking the second condition above. For performance reasons, we should, to avoid unnecessary churn.
