  <p>The two relational expressions are assumed as semantically equivalent,
  that means the hints should be attached to the relational expression
  that expects to have them.

  <p>Try to propagate the hints to the first relational expression that matches,
  this is needed because many planner rules would generate a sub-tree whose
  root rel type is different with the original matched rel.

  <p>For the worst case, there is no relational expression that can apply these hints,
  and the whole sub-tree would be visited. We add a protection here:
  if the visiting depth is over than 3, just returns, because there are rare cases
  the new created sub-tree has layers bigger than that.

  <p>This is a best effort, we do not know exactly how the nodes are transformed
  in all kinds of planner rules, so for some complex relational expressions,
  the hints would very probably lost.

  <p>This function is experimental and would change without any notes.</div>
