No, I take that back. There were no references to extra_lateral_rels after that commit; these comments were added by 45be99f8c, about six weeks later. The latter was a pretty large patch and had presumably been under development for quite some time, so the comments were probably accurate when written but didn't get updated. regards, tom lane
