In addition, why not use symlinks so that the current version is simply called "current", as in

    http://www.postgresql.org/docs/current/static/sql-insert.html

If you google for "postgres insert", you get this:

   http://www.postgresql.org/docs/8.1/static/sql-insert.html

The problem is that Google ranks pages based on inbound links, so older versions of Postgres *always* come up before the latest version in page ranking.  By using "current" and encouraging people to link to that, we could quickly change the Google pagerank so that a search for Postgres would turn up the most-recent version of documentation.
