commit    ad2ad698ac16f36a9784bc98f312cf5b5266c6aa
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Fri Feb 12 22:33:14 2021 +0000
First released in: 14.0

    Tweak compiler version cutoff for no_sanitize("alignment") support.
    
    Buildfarm results show that gcc up through 7.x produces annoying
    warnings for this construct (and, presumably, wouldn't do the right
    thing anyway).  clang seems okay with the cutoff we have, though.
