The redundant column `Column` will be presented in the table header.
Depending on output format `Tags` are serialized differently:
* For *pretty* format YAML is used, every element on the new line
* For *tsv* format for YAML is also used, but all elements and on the same line (similar to JSON)
* For *json* and *yaml* formats `Tags` are serialized into an appropriate format.
<details><summary>Examples of output in pretty formats:</summary>
```bash
$ patronictl list
+ Cluster: batman (6813309862653668387) +---------+----+-----------+---------------------+

<details><summary>Example in tsv format:</summary>
```bash
Cluster Member Host Role State TL Lag in MB Pending restart Tags
batman postgresql0 127.0.0.1:5432 Leader running 2
batman postgresql1 127.0.0.1:5433 running 2 0 {clonefrom: true, nofailover: true, noloadbalance: true, replicatefrom: postgresql0}
batman postgresql2 127.0.0.1:5434 running 2 0 * {replicatefrom: postgres1}
```

In addition to that, `patronictl list` command will stop showing keys with empty values in `json` and `yaml` formats.

$ patronictl list -f yaml
