Constraint check is missing value check ARRAY

The following documentation comment has been logged on the website:

Description:

Hi Documentation team

This page is missing the value check array.
https://www.postgresql.org/docs/current/ddl-constraints.html

Example:
CREATE TABLE demo
(
id bigint NOT NULL DEFAULT nextval('seq_ttelephone_id'::regclass),
usage character(1) NOT NULL DEFAULT 'M',
CONSTRAINT ck_ttelephone_usage_1 CHECK (usage = ANY
(ARRAY['M'::character(1),'H'::character(1),'W'::character(1),'F'::character(1)]))
NOT VALID
)
);

This is entirely missing from the documentation.

Key thing to point out is the type cast must match:
e.g. character(1) for type of character(1) etc

Please add this to the documentation, last knowledge on web for this is
10-years old, and this is a current feature of postgres (using 17.11
currently)

Many thanks
Eugene
