on v2.4.5 everything builds ok but on docker-compose up I get a couple errors.

So in my case this is not a bug in iris at all.
It's because I made some changes to my posgres-management.

Added the extention 'pgcrypto' to the database fixed the issue.
Some ansible code for you here:

- name: "Add pgcrypt-extension to the database"
  postgresql_ext:
    login_port: "{{ postgres_port }}"
    login_host: "{{ postgres_host}}"
    login_user: "{{ postgres_secrets.postgres_user }}"
    login_password: "{{ postgres_secrets.postgres_password }}"
    name: "pgcrypto"                                                                                                           
    db: "{{ iris.postgres.db_name }}"
    state: present

It might be enough to run this SQL when connected to your DB using psql:

CREATE EXTENSION pgcrypto;

Could be a good idea to catch this exception and hint to the user that they might have to fix their backend?
