- Manuals // shows a table of five releases.
  - Archive
  - French // where is English?
  - Japanese // where is English?
- Security // leads to http://www.postgresql.org/support/security/ And the menu has gone. Is this still part of "Documentation"?
- What's New // leads to http://www.postgresql.org/docs/9.2/static/release-9-2-2.html - The page on top has "Home → Documentation → Manuals → PostgreSQL 9.2".

PostgreSQL 9.3.1 Documentation

There are at least two parts labeled with a Roman number I:

http://www.postgresql.org/docs/9.3/static/sql-commands.html I. SQL Commands
http://www.postgresql.org/docs/9.3/static/tutorial.html I. Tutorial

I. Tutorial

Those who set up and manage their own server should also read Part III.

Does one need to read "I" to find out that one needs to read "III" to manage an own server? If not, then isn't it superfluous is? And yes, it is in the http://www.postgresql.org/docs/9.3/static/preface.html - redundancy bloats the documentation.

1.4. Accessing a Database

You already discovered this scheme in the previous section using createdb.

No. I did not.

II. PostgreSQL Client Applications

http://www.postgresql.org/docs/9.3/static/reference-client.html

This part contains reference information for PostgreSQL client applications 
and utilities. Not all of these commands are of general utility;

These commands? The first sentence did not contain the word "command".
