Take a look at this code in AfterTriggerSaveEvent():
/*
* If the trigger is a deferred unique constraint check trigger, only
* queue it if the unique constraint was potentially violated, which
* we know from index insertion time.
*/
if (trigger->tgfoid == F_UNIQUE_KEY_RECHECK)
{
if (!list_member_oid(recheckIndexes, trigger->tgconstrindid))
continue; /* Uniqueness definitely not violated */
}
If you trace it back, you'll see that for a statement-level trigger,
recheckIndexes will always be empty.
