There was a major docker upgrade about 1-2 months ago, and I think it upgraded to postgres 9.5? I just did a `./launcher rebuild app` today and saw that postgres 9.3 is in use… ```plaintext :/var/discourse# ./launcher rebuild app Ensuring launcher is up to date Fetching origin Launcher is up-to-date Stopping old container + /usr/bin/docker stop -t 10 app app cd /pups && git pull && /pups/bin/pups --stdin Already up-to-date.
