Rasa X Docker Compose: How to attach to postgresql db docker container

[yxs8495 (John Cleveland)]

I am using the standard docker-compose file for Rasa X. I cannot attach to the db. In endpoints.yml

$DB_USER: admin $DB_PASSWORD: ***

I try

docker exec -it <container_id> psql -U admin

I get

Password for user admin:
psql: FATAL: database “admin” does not exist

[yxs8495 (John Cleveland)]

docker exec -it <container_id> psql -d rasa -U admin

works !
