commit    d8718edf6017ba647abb2715d6196ca53bb3aec6
Author:   Alvaro Herrera <alvherre@alvh.no-ip.org>
Date:     Wed Mar 23 18:23:51 2022 +0000
First released in: 15.0, 10.21, 11.16, 12.11, 13.7, 14.3

    pg_upgrade: Upgrade an Assert to a real 'if' test
    
    It seems possible for the condition being tested to be true in
    production, and nobody would never know (except when some data
    eventually becomes corrupt?).
