with an old box on Wheezy. It only seems to have binaries up to postgres 10.
Might be nice to make a note on the web page so people realize some distro's aren't supported fully instead of (if they're like me) wondering "why don't these instructions work? It says to run apt-get install postgresql-12" ...
The page lists which distros *are* supported. You can assume that anything *not* listed is unsupported.
In the case of wheezy, whatever was the latest when it stopped being supported, is still there. Which I guess can cause some confusing if you just run the script without reading the note that's there. I'm unsure how to fix that though.
