- * Event Triggers are completely disabled in standalone mode. There are
- * (at least) two reasons for this:
- *
- * 1. A sufficiently broken event trigger might not only render the
- * database unusable, but prevent disabling itself to fix the situation.
- * In this scenario, restarting in standalone mode provides an escape
- * hatch.
- *
- * 2. BuildEventTriggerCache relies on systable_beginscan_ordered, and
- * therefore will malfunction if pg_event_trigger's indexes are damaged.
- * To allow recovery from a damaged index, we need some operating mode
- * wherein event triggers are disabled. (Or we could implement
- * heapscan-and-sort logic for that case, but having disaster recovery
- * scenarios depend on code that's otherwise untested isn't appetizing.)
+ * See EventTriggerDDLCommandStart for a discussion about why event
+ * triggers are disabled in single user mode.
