If you don't like that you can try including a "Reply-To: <list>" header in what you send to the list; or perhaps better, I think there's a way to tell the list bot to not send you copies of messages you're cc'd on. But the old-timers are all accustomed to this behavior. The PG lists are big enough that turnaround time is O(minutes) even when everything is going well, and sometimes it isn't --- so direct cc's to the people involved in a specific thread help keep the conversation moving. Also, some of us find a backup copy sent via the list to be a Good Thing. I for one have a reputation of running spam filters that eat pets and small children ... so if you want to be sure to get through to me, don't forget to cc: the list. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
