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.
