www: can you please remove Wily from the dropdown box?
Done. Will update on the next reload.
To be over-clear, that leaves xenial, trusty and precise on the Ubuntu download page.
Re Yakkety, we don't have a real policy yet on which non-LTS releases we are supporting (there's so many of them...). Historically we've added them once the most recent LTS packages started to be uninstallable due to dependencies. Rebuilding packages for the newly added distributions was always painful, but we have more experience with that now.
Do we see a real user demand for the non-LTS releases so it would make sense to add them? (In the past, that wasn't always the case.)
Normally those versions already carry the latest version of postgres at their release time, right? So it's not like they are without postgres, or are stuck with a really old version?
