Author: Andrew Dunstan <andrew@dunslane.net>
Date: Mon Sep 02 18:36:08 2013 +0000
First released in: 9.4.0, 8.4.18, 9.0.14, 9.1.10, 9.2.5, 9.3.0
Fix relfrozenxid query in docs to include TOAST tables.
The original query ignored TOAST tables which could result in tables
needing a vacuum not being reported.
Backpatch to all live branches.
