Installing Postgres 9.5 On OSX

02 Aug 2015

Edit 12/25/2020: I’d recommend using: https://postgresapp.com/

Ended up being surprisingly easy:

brew uninstall postgresql brew install postgresql-9.5 brew link -f postgresql-9.5 mv /usr/local/var/postgres /usr/local/var/postgres.old initdb -D /usr/local/var/postgres # restore old database? # pg_upgrade -b /usr/local/Cellar/postgresql/9.0.4/bin -B /usr/local/Cellar/postgresql/9.1.2/bin -d /usr/local/var/postgres.old -D /usr/local/var/postgres # start postgres pg_ctl -D /usr/local/var/postgres -l logfile start
