    The known commands are:
        create
	  Create database schema (needs to be executed only once)
        migrate
	  Execute database migrations (needs to be done after updates)
        rollback [VERSION]
	  Rollback database migrations (needs to be done before downgrading)
	update [OPTIONS]
	  Update the instance.
	  Options:
	  --branch  Update to a specified branch, instead of the latest version of the current one.
	  --flavour Update to a specified flavour (CPU architecture+libc), instead of the current one.
	  --zip-url Get the release from a specified url. If set, renders the previous 2 options inactive.
	  --no-rm   Do not erase previous release's files.
	  --tmp-dir Download the temporary files to a specified directory.
    and any mix tasks under Pleroma namespace, for example \`mix pleroma.user COMMAND\` is
    equivalent to \`$(basename "$0") user COMMAND\`
    By default pleroma_ctl will try calling into a running instance to execute non migration-related commands,
    if for some reason this is undesired, set PLEROMA_CTL_RPC_DISABLED environment variable.
