Argh, no? I was thinking of something much more trivial:

    pgbench_error(DEBUG, "message format %d %s...", 12, "hello world");

If you really need some complex dynamic buffer, and I would prefer 
that you avoid that, then the fallback is:

    if (level >= DEBUG)
    {
       initPQstuff(&msg);
       ...
       pgbench_error(DEBUG, "fixed message... %s\n", msg);
       freePQstuff(&msg);
    }

The point is to avoid building the message with dynamic allocation and so
if in the end it is not used.
