Compute POSTGRES_ALLOWED_AVG_CONNECTIONS once and propagate to app roles (gitlab, mastodon, listmonk, matrix, pretix, mobilizon, openproject, discourse). Fix docker-compose postgres command (-c flags split). Add unit tests. Minor env/locale tweaks and includes. Conversation: https://chatgpt.com/share/68b48e72-cc28-800f-9c21-270cbc17d82a
