5e0dc11f87 is described below

commit 5e0dc11f87b2135050cd9e421134bd80409f1fd4
Author: mch_ucchi <41606806+sohardforan...@users.noreply.github.com>
AuthorDate: Thu Sep 15 11:56:56 2022 +0800

    [feature](Nereids)add RelationId as a unique identifier of relations 
(#12461)
    
    In Nereids, we could not distinguish two relation from same table in one 
PlanTree.
    This lead to some trick code to process them when do plan. Such as a 
separate branch to do equals in GroupExpression.
    This PR add RelationId to LogicalRelation and PhysicalRelation. Then all 
relations equals function will compare RelationId to help us distinguish two 
relation from same table.
    
    TODO:
    add relation id to UnboundRelation, UnboundOneRowRelation, 
LogicalOneRowRelation, PhysicalOneRowRelation.
