For Mac users, the way you connect to the database is simply by opening the elephant icon on the bar and making sure that your database is running, and then clicking on “Open Postgres”.
 
 
Right after that, you will see that you have 3 databases by default.
 
 
 
Just click on any of the default databases and you will see that your terminal will open.
 
As you can see in the above image you are in a database mode right now.
 
 
Now open a new shell and type “psql”.
 
Now you will see that the “command not found”.
 
 
This error occurs because we need to add to the path.
 
So to do so we are simply going to add to the path.
 
This assumes that everyone is using iTerm as well as “Oh My ZSH”
 
Now close the terminal and open iTerm.
 
And type the command given below
 
Cd ~
ls -a
 
 
You can see the file in there but the one which we need is “.zshrc”.
 
Now again give a command: “vi .zplshrc” 
 
 
 
Now you need to add export in the “path”.
 
Copy the path of the database from the Postgres default database.
 
As shown in the image given below.
 
 
Now paste the path you copied for the default database.
 
And remove the psql from the path.
 
 
Now to come out from this file you just need to press ESC and then:wq
 
There you go you came out of the file and also added the path.
