Hi, I'm reading the documentation and I'm trying to wrap my head around this statement:
"Finally, NATURAL is a shorthand form of USING: it forms a USING list consisting of all column names that appear in both input tables. As with USING, these columns appear only once in the output table. If there are no common column names, NATURAL JOIN behaves like JOIN ... ON TRUE, producing a cross-product join." Did it mean cartesian product and not cross-product?
