It kind of flies in the face of the idea that a RangeTblEntry is just a node that can be freely copied around, serialized and deserialized, etc. I think it would be better to keep the pointer in the RelOptInfo in the planner and in the EState or PlanState in the executor. Those are things we don't think can be copied, serialized, etc. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
