NULLs and sort order

I'm forwarding this information from Peter Eisentraut on
pgsql-hackers about NULLs and sort order. I couldn't find this
in the documentation.

I guess it should be in "ORDER BY Clause" of "SELECT" in the
Reference Manual, and in the 7.2 release notes.

Can someone add this to the documentation?

Or am I expected to submit a patch on the Docbook sources?
