I know that I first look at the docs & seldom look at the Wiki - in fact
it was only recently that I became aware of the Wiki, and it is still
not the first thing I think of when I want to know something, and I
often forget it exists. I suspect many people are like me in this!

Also the docs have a more authoritative air, and probably automatically
assumed to be more up-to-date and relevant to the version of Postgres used.

So I suggest that the docs should have an appropriate coverage of such
topics, possibly mostly in an appendix with brief references in affected
parts of the main docs) if it does not quite fit into the rest of the
documentation (affects many different features, so no one place in the
main docs is appropriate - or too detailed, or too much). Also links to
the Wiki, and to the more academic papers, could be provided for the
really keen.

Cheers,
Gavin
