It might not be if you view it in isolation (although I'm not
convinced). The problem is that it has cost beyond pgbench. Due to
pgbench's overflow handling I can't run make check on a build that has
-ftrapv, which found several bugs already.

I'd be happy if somebody else would tackle the issue, but I don't quite
see it happening...
