commit    d1f638bcd8db6e5c9cd471c067829a42e34fdbcd
Author:   Andrew Dunstan <andrew@dunslane.net>
Date:     Mon Sep 02 18:35:26 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.
