关于postgresql：事务上下文中postgres日志中“execute”和“statement”之间的区别

Difference between “execute” and “statement” in postgres logs in transaction context

我收到"警告：没有正在进行的事务"错误，如此处所述。当我查看日志时，我看到我的风帆水线ORM导致"声明"字出现在日志中如果我使用其Model.query方法并且"执行"字出现在通过其模型方法发出的查询前面比如.insert，.update等。它们之间在交易中的行为方式有什么区别吗？或者，日志中"声明"和"执行"之间的区别是什么？

您最有可能在自动提交模式下运行查询。在此模式下，每个语句都有自己的小事务。发出WARNING是因为所有语句都已提交，commit语句没有"看到"它们。
