Postgres is no longer starting

Fails with:
db_1   | Error: Database is uninitialized and superuser password is not specified.
db_1   |        You must specify POSTGRES_PASSWORD for the superuser. Use
db_1   |        "-e POSTGRES_PASSWORD=password" to set it in "docker run".
db_1   |
db_1   |        You may also use POSTGRES_HOST_AUTH_METHOD=trust to allow all connections
db_1   |        without a password. This is *not* recommended. See PostgreSQL
db_1   |        documentation about "trust":
db_1   |        https://www.postgresql.org/docs/current/auth-trust.html
