Subject: [PATCH] doc:  remove xreflabels from commits 75fcdd2ae2 and
 85af628da5

xreflabels prevent references to the chapter numbers of sections id's.
It should only be used in specific cases.

Discussion: https://postgr.es/m/8315c0ca-7758-8823-fcb6-f37f9413e6b6@2ndquadrant.com

Backpatch-through: 9.5
