create a PostgreSQL user django on mac

$ psql -h localhost

Here is what the above code is Doing:
1. We’re importing the psycopg2 library, which is the Python library for Postgres.
2. We’re creating a connection to our database.
3. We’re creating a cursor, which is a way to interact with the database.
4. We’re executing a query, which is a SQL command to get all the rows from the table.
5. We’re iterating over the result set, and printing out the name of each person.
6. We’re closing the cursor and the connection.
