Mistake in documentation (PG15+)
The following documentation comment has been logged on the website:

Description:
Greetings.
Just found a mistake in documentation:
https://www.postgresql.org/docs/15/datatype-numeric.html
$$
Thus, a column declared as
NUMERIC(2, -3)
will round values to the nearest thousand and can store values between
-99000 and 99000, inclusive.
$$
But the correct range here would be from -99499 to 99499:
select 99499::NUMERIC(2, -3);

I'm not sure I see the error you indicate, numeric(2,-3) gives the range
indicated in the documentation:
postgres=# select -99499::numeric(2, -3) as neg, 99499::numeric(2, -3) as pos;
neg | pos
--------+-------
-99000 | 99000
(1 row)
