   # Proposed changes
   The main purpose is to facilitate debug, tracing every groupExpression and 
plan node.
   
   rename RelationId to ObjectId, and assign id to every groupExpression and 
PlanNode
   for example, in plan.treeString(), 5253 is the id for this project. It helps 
us to set break point condition.
   `
    +--PhysicalProject[5253] ( projects=[i_product_name#21], stats=(rows=5760, 
width=2, penalty=0.0) 
   `
