A password is now required by the postgres Docker image which makes
initial setup (and our CI build) fail with the following error:
postgres_1 | Error: Database is uninitialized and superuser password is not specified.
postgres_1 | You must specify POSTGRES_PASSWORD for the superuser. Use
postgres_1 | "-e POSTGRES_PASSWORD=password" to set it in "docker run".
postgres_1 |
postgres_1 | You may also use POSTGRES_HOST_AUTH_METHOD=trust to allow all connections
postgres_1 | without a password. This is *not* recommended. See PostgreSQL
postgres_1 | documentation about "trust":
postgres_1 | https://www.postgresql.org/docs/current/auth-trust.html
See https://github.com/docker-library/postgres/issues/681.
This fixes currently failing Docker builds.
kemalcr/kemal in version 0.26.0 requires Crystal 0.30.0 which is not
yet available on Alpine 3.10 (previously used as the Docker base image).
