Robert Lor and Josh Berkus have taken up my offer to assist in
documenting the new Dynamic Trace facility more fully, which was the one
remaining item on the 8.2 Open Items list.
I'm planning to
- add a new section to Performance Tips chapter called Dynamic Tracing
- rename the chapter Performance & Tuning.
- add some further intro stuff on chapter header page
Comments?

In my mind it's a little late for revising the documentation structure.
I'd also think that DTrace is not a tuning tool but a monitoring tool
which might place it closer to the description of the statistics
collector. I think the original plan even placed it into the Internals
part.

An additional chapter then, in the internals section? Dynamictrace.sgml
Or a subsection in the Monitoring.sgml chapter? (with the statistics
collector stuff)

I was about to say the same. In my mind DTrace is primarily a hacker's
tool --- I do not foresee the average DBA using it. So it does not
belong in the Performance Tips chapter. A new chapter under Internals
is probably as good as anything.

I'm not certain how best the postgresql specific probes will be used, but I
might disagree with the above take as we're already using some kernel level
dtrace probes to make DBA oriented tools... see
http://www.lethargy.org/~jesus/archives/74-PostgreSQL-performance-through-the-eyes-of-DTrace.html
for one specific example.
