E.1.2. Migration to Version 14

Hello!
E.1.2 Migration to Version 14
<https://www.postgresql.org/docs/14/release-14.html#id-1.11.6.5.4>
array_append() <https://www.postgresql.org/docs/14/functions-array.html>,
array_prepend(), array_cat(), array_position(), array_positions(),
array_remove(), array_replace(), and width_bucket()
<https://www.postgresql.org/docs/14/functions-math.html>

Is this a complete list of functions? Or you need to remove all functions:
Table 9.52. Array Functions
<https://www.postgresql.org/docs/14/functions-array.html>

Do the functions need to be deleted and restored, or can they be recreated?
I have a lot of them and they are called from other functions:

Uchet=# SELECT COUNT(pg_proc.proname) AS "COUNT"
Uchet-# FROM pg_proc
Uchet-# WHERE pg_proc.prosrc ~~ '%array%'::text AND pg_proc.pronamespace
= 16443::oid;
COUNT
-------
89
(1 row)
Trying to estimate labor costs and migration opportunities.
Thanks!
