to be clear, this is not the best solution as it uses O(n^2 log n) time; Blind4Basics solution is better.

What's the point of the r? I did basically the same thing except without the r, and it worked fine.

Fixed

Minor suggestion: without the list brackets, it's a generator expression, and is a little more efficient. Consuming the generator into a list isn't necessary.

yes, comparison operators yield booleans in PostgreSQL

So just trying to clarify it for myself, you don't need to use "CASE WHEN" in this case? If you just write that inequality, the new column will automatically contain either "true" or "false"? Thanks in advance.

I always forget that the ternary exists

wow this was a clever and concise solution!
