Unfortunately, EDB -- the company that provides the Windows installer for PostgreSQL -- currently is not including the Language Pack in its StackBuilder installer. I have filed this ticket on the issue:
If this issue arose while installing PostgreSQL downloaded from EDB, you can safely continue with the installation and skip the Language Pack for now. The Language Pack provides support for the Python programming language, which accounts for one small lesson late in the book, and its absence will not prevent you from running 99% of the code.
I'll post here when/if I get clarity on this from EDB.
