failed to get event triggers from database %q

Error message

failed to get event triggers from database %q

What it means

SyncDBSchema collects event triggers via getEventTriggers(txn, extensionDepend), reading pg_event_trigger and dependency info to distinguish user triggers from extension-managed ones. This wrapper is applied when that final catalog query fails, aborting the sync just before the transaction commits.

Solutions

Inspect the wrapped cause for the concrete driver error.
Restore default catalog read privileges if revoked for the sync role.
Increase statement_timeout/idle_in_transaction_session_timeout and retry the sync.
Reduce sync scope or frequency for very large databases to keep the transaction short.

Defensive patterns

Strategy: try-catch

Validate before calling

SELECT count(*) FROM pg_event_trigger; -- readable and cheap to scan

Try / catch

ets, err := getEventTriggers(txn, extensionDepend)
if err != nil {
	return fmt.Errorf("event trigger collection failed near end of sync: %w", err)
}

Prevention

Set idle_in_transaction_session_timeout above expected sync duration
Avoid network paths that reset connections mid-transaction
Keep the overall sync transaction short on large databases
Verify catalog privileges before first sync of a new database

When it happens

Trigger: Calling SyncDBSchema when the event-trigger catalog query errors: connection reset near the end of a long sync, statement timeout, or missing catalog access.

Common situations: Long syncs on large databases hitting idle-in-transaction or network timeouts right at this final step; hardened roles; servers terminating long-running read transactions.
