commit    de7c6fe8347ab726c80ebbfcdb57f4b714d5243d
Author:   John Naylor <john.naylor@postgresql.org>
Date:     Wed Mar 06 08:54:25 2024 +0000

    Fix signedness error in 9f225e992 for gcc
    
    The first argument of vshrq_n_s8 needs to be a signed vector type,
    but it was passed unsigned. Clang is more lax with conversion, but
    gcc needs a cast.
    
    Fix by me, tested by Masahiko Sawada
    
    Per buildfarm members splitfin, batta, widowbird, snakefly, parula,
    massasauga
