After `CTESubstitution`, we will create a `CTERelationDef` whose `child` is a union query with `CTERelationRef` referencing itslef. IIUC our goal is to rewrite this recursive `CTERelationDef`'s `child` to be a `UnionLoop` with `UnionLoopRef`. Why do we need to put this `anchor` field in `CTERelationDef`? -- This is an automated message from the Apache Git Service.
