If you built your own binaries from source, there is a directory called
contrib under the root of your source tree. You'll need to build the
modules.
If you installed a package, you'll probably need to grab a contrib
package for your version as well (I'm not overly familiar with the
pre-packaged binaries). Look in the following directory for your
binaries:
/path_to_postgres/doc/contrib
If the contrib stuff is installed, you'll find the appropriate docs
there.
