FWIW, I think I fixed jsonb_set_lax yesterday, so that problem should
be gone the next time the cfbot tries this.

Why not?  We're not going to allow pushing a patch that throws warnings

to have to spend time cleaning it up.  Better to clean it up sooner.

(There is, btw, at least one buildfarm animal using -Werror.)
