It embeds knowledge here that should not exist outside elog.c; moreover, I'm not entirely sure that it's even correct, given the nonlinear ranking of log_min_messages. Maybe it'd be a good idea to have elog.c expose a new function along the lines of "bool message_level_is_interesting(int elevel)" to support this and similar future optimizations in a less fragile way. regards, tom lane
