Several of the buildfarm animals seem to have been updated to
GCC 15 over the past week or so. They are now moaning about
various places where we're intentionally omitting a string
terminator, eg these warnings from scorpion:

../pgsql/src/backend/commands/copyfromparse.c:139:41: warning:
initializer-string for array of 'char' truncates NUL terminator but destination
lacks 'nonstring' attribute (12 chars into 11 available)
[-Wunterminated-string-initialization]
Note that this is not a default warning option in gcc or an option put
in by PostgreSQL. This comes from -Wextra, which that buildfarm member
has added by itself. So there is also an option C in having that
buildfarm member turn off that option.
That said, I think addressing this with some attribute decoration could
be useful. But then we should also add this option explicitly to our
warning option set, so that going forward we can maintain this locally
and not via a lone buildfarm member.
