I have recently installed PostgreSQL on my Mac via Homebrew. (I may have already had it installed; it was not running.) brew install postgres ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents Now I am trying to start it with launchctl: launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist ...but I am getting an error: /usr/local/Cellar/postgresql/9.4.0/homebrew.mxcl.p
