I did not read through the whole article, but I already have some comments;
work_mem was formerly sort_mem. As many of us still use pg7, you should
probably have a note about it.
There are already quite some short articles at the web about this issue, and
that was actually my starting point when I was assigned the task of tweaking
the database performance. I think diversity is a good thing, some of the
short articles was relatively outdated, others were not very well written.
And also - I still never had the chance to do proper benchmarking of the
impact of my changes in the configuration file, I just chose to trust some
of the advices when I saw almost the same advice repeated in several
articles.
I think we need some comprehensive chapter about this in the manual, with
plenty of pointers - or eventually some separate well-organized pages
telling about all known issues. It seems to me that many of the standard
tips here are repeating themselves over and over again.
