zsh：找不到 postgres 命令

Question

mac bigSur 11.6.4, zsh

Issue: I am trying to start postgres server via command "postgres". I am getting the following error "zsh command not found postres"

I installed postgres@12 via homebrew. I see postgresql@12 in /usr/local/var/

The only things in /usr/local/var are: homebrew, log, and postgresql@12

My.zshrc file looks like this as it stands

export PATH=/usr/local/bin:$PATH
source /usr/local/opt/chruby/share/chruby/chruby.sh
source /usr/local/opt/chruby/share/chruby/auto.sh
export PGDATA=/usr/local/var/postgresql@12
export PGHOST=/tmp

Does anyone know if I am missing something?

Answer 1

You need to use homebrew's services command.

This will list available services (in case you have multiple postgres versions installed) and their statuses:

brew services

To start a service, run this command:

brew services start postgresql@12
