commit    5533a272ddecff18f16e9b6c307dcb2e130538f4
Author:   Heikki Linnakangas <heikki.linnakangas@iki.fi>

    Don't assume that 'char' is signed.
    
    On some platforms, notably ARM and PowerPC, 'char' is unsigned by
    default. This fixes an assertion failure at WAL replay on such platforms.
    
    Reported by Noah Misch. Backpatch to 9.5, where this was broken.
