HV010 — fdw_function_sequence_error

速览 {#at-a-glance}

HV010 表示 FDW 函数以无效顺序被调用。固定的 18.6 核心与 contrib 调用扫描没有解析出 HV010 报告组，因此不能确认核心回调或消息。

含义 {#meaning}

该条件涉及包装器操作的顺序或生命周期。fdwapi.h 定义规划和外部扫描等回调入口，但这只是 API 背景，不会发出 HV010，也不规定每个包装器的合法顺序。

消息与诊断 {#messages}

没有解析出 18.6 核心与 contrib 的直接消息变体。保留完整消息、回调名称、操作阶段、包装器/驱动版本，以及调用发生在规划、扫描启动、迭代、重扫描、修改还是清理之后。

诊断 {#diagnosis}

围绕失败回调追踪包装器状态机。确认哪个对象已经初始化、回调是否重复或遗漏，以及清理是否早于后续调用。应以包装器自身契约和源码映射判断顺序错误发生在本地还是远端。

处理 {#response}

恢复已安装包装器及其回调契约要求的调用顺序，再从新对象状态验证同一操作。不要盲目重复回调：包装器可能已经发出远端请求或释放了状态。

版本 {#versions}

HV010 在锁定定义快照 9.1.24 至 18.6 以及 19 Beta 3 中存在，known_present_by 为 9.1.0。现有 9.1 之前定义资料不能证明精确引入版本。

相关 {#related}

HV00B 涉及无效句柄；HV00K 涉及回复句柄；HV009 涉及无效空指针使用。
