gen_random_uuid is only available with pgcrypto enabled
The following documentation comment has been logged on the website:

Description:
Regarding the documentation on this page:
https://www.postgresql.org/docs/15/functions-uuid.html
It think the documentation should state clearly, that postgres natively does
not have any UUID generation functions. You can use the `pgcrypto` or
`uuid-ossp` extensions though:
CREATE EXTENSION "pgcrypto"; /* enable pgcrypto extension */
SELECT public.gen_random_uuid(); /* -> uuid */
See https://www.postgresql.org/docs/current/pgcrypto.html#id-1.11.7.37.11
CREATE EXTENSION "uuid-ossp"; /* enable uuid-ossp extension */
SELECT public.uuid_generate_v4(); /* -> uuid */

That hasn't been true since we added gen_random_uuid() to the
core code in v13. pgcrypto's version is now just a deprecated
wrapper for that.

But that isn't true...
