Any support with podman-compose?

I'm running podman compose 1.3.0 (latest version) and lots of errors, certainly due to the lack of podman support.

[postgres]   | Error: Database is uninitialized and superuser password is not specified.
[postgres]   |        You must specify POSTGRES_PASSWORD to a non-empty value for the
[postgres]   |        superuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".
[postgres]   | 
[postgres]   |        You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all
[postgres]   |        connections without a password. This is *not* recommended.

Is there a plan to support podman for guys like me?

Start by reproducing the reported setup with podman-compose 1.3.0 and the repository's compose configuration, checking the PostgreSQL password handling and Mattermost config-file permissions shown in the logs. Done means the deployment works under Podman or the supported limitations and required configuration are clearly documented.
