I'd suggest that in the "Latest Releases" section that next to the existing "Notes" link we add a "Documentation" (or "Docs") link that takes one to the Table of Contents page for the version.
I personally have a desire for 1 bookmark to the PostgreSQL site, which takes me to the homepage, and then ideally single-click to get to the documentation.
Making our above-the-fold content a bit shorter to get the latest releases section back into the no-need-to-scroll area would be nice too. For me the site is more functional that marketing - which the old design catered better than this one does.

P.S. Repeating the current version numbers twice in the latest releases seems unhelpfully redundant.
