I don't quite follow the need for this. I mean, if we just stick a Param reference in there and create a corresponding InitPlan, the Param will be evaluated on demand, right? Is the point of the new node to make sure that the Param gets re-evaluated when needed? -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
