Folks who are looking for ways to upgrade PostgreSQL without downtime might want to take a look at this setup using pacemaker: https://github.com/gocardless/our-postgresql-setup http://www.interdb.jp/blog/pgsql/pg_pacemaker_01/ digs into playing with the vagrant box a tiny bit. EDIT-- ah, found the talk explaining it: https://www.youtube.com/watch?v=SAkNBiZzEX8
