From a2dec374807565f6337915fb236bb3ae37af0644 Mon Sep 17 00:00:00 2001 From: Thomas Munro Date: Tue, 25 Jun 2019 09:17:04 +1200 Subject: [PATCH] Remove misleading comment from pathnodes.h. As of commit e5253fdc, it is no longer true that the leader always executes the subplan of a Gather Merge node. Remove comment to that effect. Back-patch to 11.
