Authentik serves multi-second API reads from the CNPG hot standbys. Those reads outlive `max_standby_streaming_delay`, so recovery cancels them with `canceling statement due to conflict with recovery`, which authentik surfaces as HTTP 500 — enough to break a terraform apply mid-run.
- set `hot_standby_feedback` on so replicas report their oldest xmin to the primary and long reads stop being cancelled
- SIGHUP reload only, no restart or switchover
- retained-dead-tuple cost is negligible on a ~155MB database
