[Removing all the other xposted lists -- don't do that!]

And fwiw the reason it's not an urgent issue for Postgres is because
we build with -fwrapv, essentially asking the compiler for a C
language that offers more guarantees than the standard (but matches
traditional C environments). So there isn't an active bug on Postgres
with GCC (or I think Clang) but may be with other compilers if they
don't have that option.
