Boolean
monotonic
Indicates whether or not this function is monotonic on all of its arguments. This means that it is either entirely non-increasing or non-decreasing. Even if the function is not monotonic on all of its arguments, it’s possible to specify that it is monotonic on one of its arguments, meaning that partial applications of the function over that argument will be monotonic.
Monotonicity is required to use the function in a GROUP BY clause.
The argument names that the function is monotonic on.
If monotonic
is true, this will return all argument names.
Otherwise, this will return either one argument or an empty array.
