Section 5.5.3 [1] currently says:

"NULL values are "less than" all other values in comparisons.

Empty strings (zero length strings) are not NULL values. An empty string is
"less than" a string with length greater than zero."

This seems to imply that the value of the expression


is TRUE. However, I think it should be UNKNOWN.

Shouldn't the statement be rewritten to only refer to the case of *sorting*
