I think it ties to pg_class, but I am not sure how to relate them. Also, I have not had a chance to us the \dt function. Can you give me some pointers or point me to the docs?
Why didn't you just try it?

You shouldn't be sending spam, you know ;) Or isn't that what's meant here?
That's a pretty useless number anyhow, the spam filter I use (dspam) catches about that much in a weeks time for my account alone. Without a total or a starting date its just a meaningless number.
Do you have any influence on what it prints under your messages?
