commit    cfe992e7eb24fa92f93ee9d31f1f0f515a49c11d
Author:   Heikki Linnakangas <heikki.linnakangas@iki.fi>
Date:     Tue Apr 01 18:16:10 2014 +0000
First released in: 9.4.0

    Remove dead check for backup block, replace with Assert.
    
    We don't use backup blocks with GIN vacuum records anymore, the page is
    always recreated from scratch.
