Usage of planner_ctx
Started by Amit Kapilaover 13 years ago2 messages
PlannerInfo->planner_ctx is assigned with either MessageContext or
PortalHeapMemory depending on the flow from which planner is invoked.
My doubt is that during whole planning process till the Plan is stored in
PlannedStmt, all the memory is from CurrentMemoryContext which is same as
PlannerInfo->planner_ctx.
So what is the use of having PlannerInfo->planner_ctx which only contains
CurrentMemoryContext?
