Indeed. 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.
