To start the PostgreSQL server on macOS, you can follow these steps:

  1. Open a terminal window.
  2. Navigate to the directory where PostgreSQL is installed. By default, it is installed in the /usr/local/pgsql directory.
  3. Run the following command to start the PostgreSQL server:

sudo pg_ctl -D /usr/local/pgsql/data start

Note that you may need to provide your administrator password when prompted.

  1. The PostgreSQL server should now start running. You can verify its status by running the following command:

sudo pg_ctl -D /usr/local/pgsql/data status

If the server is running, you should see a message indicating that it is running and the port number it is listening on.

That's it! The PostgreSQL server should now be running on your macOS machine.
