Hi Sir, I just recently enrolled in your SQL and Postgresql for beginners course on Udemy and so far you've been such a great teacher. Do you have a plan to create a more advanced Postgresql course?

How would you CONCAT an unknown set of values into one result? If I do a SELECT name FROM public.list and get 3 rows back (Betty, George, and Mary), how can you set up the select to put them all in one string without knowing how many values it will return?
