The quoted documentation text is different between v15 and prior versions. Observe also the v15 release notes: https://www.postgresql.org/docs/15/release-15.html E.4.3.4. Data Types Allow the scale of a numeric value to be negative, or greater than its precision (Dean Rasheed, Tom Lane) This allows rounding of values to the left of the decimal point, e.g., '1234'::numeric(4, -2) returns 1200. regards, tom lane
