Description

From section 19.3.3 Start PostgreSQL if Needed

• When I type in pg_isready I get the error "zsh: command not found: pg_isready"
• I've retraced the steps in both chapters 18 and 19, but I can't see that I missed anything

 $ pg_isready
zsh: command not found: pg_isready

It seems postgres is not installed at all.  I seem to be in the proper directory and when I try to check the version of postgres I get the following:

(everycheese) joshpanknin@joshs-mbp-2 everycheese % ls
CONTRIBUTORS.md         env.sample.windows      requirements
COPYING                 everycheese             requirements.txt
README.md               locale                  setup.cfg
config                  manage.py
env.sample.mac_or_linux pytest.ini
(everycheese) joshpanknin@joshs-mbp-2 everycheese % postgres -V
zsh: command not found: postgres
