What does the repmgr the symbol "*" mean in the repmgr cluster status output?

I'm new to postgres administration and was wondering what does the "*" symbol means in the repmgr cluster show command output. ID | Name | Role | Status | Upstream | Location | Connection string ----+---------+---------+-----------+----------+----------+------------------------------------------------------------------ 1 | node-1 | standby | running | node-2 | default | host= [...] 2 | node-2 | primary | * running | | default | host= [...] 3 | node-3 | witness | * running | node-2 | default | host= [...] I didn't find anything about it in the documentation (https://repmgr.org/docs/4.0/repmgr-cluster-show.html) Using repmgr cluster show --csv as mentioned in the documentation, I can see that the node with ID 1 is in recovery state "*in recovery*". Is it related ? postgresql version : 10.5 repmgr version : 4.0
