From 79c50ca57828e9f8375766b36cce1e2960eebf87 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 2 Jun 2021 11:52:35 -0400 Subject: [PATCH] Update plannodes.h's comments about PlanRowMark. The reference here to different physical column numbers in inherited UPDATE/DELETE plans is obsolete as of 86dc90056; remove it. Also rework the text about inheritance cases to make it clearer. --- src/include/nodes/plannodes.h | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) diff --git a/src/include/nodes/plannodes.h b/src/include/nodes/plannodes.h index 57f320a175..aaa3b65d04 100644 --- a/src/include/nodes/plannodes.h +++ b/src/include/nodes/plannodes.h @@ -1086,9 +1086,9 @@ typedef enum RowMarkType * When the planner discovers that a relation is the root of an inheritance * tree, it sets isParent true, and adds an additional PlanRowMark to the * list for each child relation (including the target rel itself in its role - * as a child). isParent is also set to true for the partitioned child - * relations, which are not scanned just like the root parent.
