postgresql слушает только на localhost после перезагрузки (перезапускающий postgresql, решает проблему),

Я вижу это странное поведение где, после перезагрузки, PG, запущенный через postgresql@11-main (systemd) слушает только 127.0.0.1:5432 даже через PG conf файл ясно имеет следующее:

listen_addresses = '[EXTERNAL IP ADDRESS - REDACTED], 127.0.0.1'

После того как я перезапускаю через systemctl restart postgresql@11-main это слушает на 5 432 на обоих IP-адреса.

PS: Я отключил волшебство postgresql.service после того, чтобы читать некоторые сообщения, что это вызывает проблемы/беспорядок. Однако это не решило проблему.
