[%l-1] is originally from pgfouine, and I vaguely remember that it used to be something like [%l-%c] where %c was some extra line numbering removed in later (7.something?) PG versions. In any case, the -1 isn't useful. I'm happy to remove %l as well. Log lines won't be out of order anyway, and one needs to look at %p anyway to correlate them. %l doesn't help there. Christoph
