Re: [RFC] obtaining the function call stack

Hello

I did some similar (but Oracle like) in orafce - so it can help. I
thing, so this should be very useful, but result set isn't best
format. Usually you would to print to log and you have to iterate via
set. So maybe better format could be some structured text.
