Lemmy Support

Hi, As a small project i've set up an instance using the docker documentation available here: https://join-lemmy.org/docs/administration/install_docker.html

As I was troubleshooting in early stages, i've added some instances to the Allow list. Now If I undestand correctly, only these instances will be allowed for federation. How do I clear that list to go back to "Open", in order to not have to explicitely list the allowed instances?

As an additional question, is there an easy way to reset the postgresql DB password?

Thanks!
