Thank you! That's both extremely useful and helped me identify the source of my problem. A previous experiment with repmgr had left a stale primary_conninfo string in postgresql.auto.conf, which was somehow interfering with my other recovery settings. After cleaning that up, my standby can connect to my primary without issue.
