Review Comment:
In the context, `fromGroup` is the group of `LogicalRelation`, and the
`targetGroup` is the group of `LogicalRowPolicy`,
`eliminateFromGroupAndMoveToTargetGroup` will move the
logicalExpression(LogicalRowPolicy) to the targetGroup, and the origin
logicalExpression in the targetGroup will be recycle until the
`LogicalRelation`.
So I don't think we should `moveParentExpressionsReference(fromGroup,
targetGroup)`
