Yep, I thought of it, but I was not very keen on having a malloc/free 
cycle just for one debug message. However under debug this is probably not 
an issue.

Your patch works for me. IT can avoid some level of format interpretation 
overheads by switching to Char/Str functions, see first attachement.

The other point is the test on __pg_log_level, see second attached.
