42830 — 无效外键（invalid_foreign_key）

速览 {#at-a-glance}

42830 是 invalid_foreign_key（无效外键）：外键定义在被引用列上找不到合格唯一键。本案例的父表整数列没有唯一约束。

含义 {#meaning}

创建时先检查父键，尚未插入子行。固定主报文为 there is no unique constraint matching given keys for referenced table "%s"。普通 FK 的被引用列集合可以匹配物理顺序不同但合格的唯一索引；源码匹配器会拒绝被引用列重复，并要求列数正确、唯一、有效且没有部分谓词或索引表达式。若匹配到可延迟的唯一/主键索引，则进入仅源码确认的 55000 分支。这是定义时错误，不同于 23503；自动提交 ALTER 失败后为 IDLE。

诊断 {#diagnosis}

将被引用列集合与 pg_constraint、pg_index 对照。检查重复引用、列数、唯一/主键属性、有效性、部分谓词和表达式；普通路径不要求物理索引顺序与 FK 列表相同。还要检查 indimmediate：匹配但可延迟的键会报 55000，不是本案例的 42830。类型相同本身不能使键符合要求。

处理 {#response}

在被引用列集合上添加或使用有意且不可延迟的唯一键，再创建 FK。核对父表键的业务含义及 NULL/MATCH 语义；过宽唯一约束可能改变可接受数据。不要为了匹配 FK 书写顺序而重排本来合格的索引，也不要把部分或表达式索引当作合格键。案例添加 UNIQUE (id) 后创建 FK。显式事务中被拒绝的 ALTER TABLE 会使事务进入 INERROR，应先回滚或回到合适的 savepoint 再重试；本案例的自动提交路径回到 IDLE。

实测诊断 {#messages}

选定 tablecmds.c 组是 ERROR，主报文为 there is no unique constraint matching given keys for referenced table "%s"，没有 DETAIL/HINT。同一匹配器还有仅源码确认的 55000（object_not_in_prerequisite_state）变体：当唯一键本来匹配但可延迟时为 cannot use a deferrable unique constraint for referenced table "%s"。

代表案例 {#case}

注册表创建父子表，先尝试 FK，再添加父唯一键、创建有效 FK 并统计。

CREATE TABLE syntax_schema.fk_parent (id integer);
CREATE TABLE syntax_schema.fk_child (parent_id integer);
ALTER TABLE syntax_schema.fk_child ADD CONSTRAINT fk_bad FOREIGN KEY (parent_id) REFERENCES syntax_schema.fk_parent (id);
ALTER TABLE syntax_schema.fk_parent ADD CONSTRAINT fk_parent_id_key UNIQUE (id);
ALTER TABLE syntax_schema.fk_child ADD CONSTRAINT fk_good FOREIGN KEY (parent_id) REFERENCES syntax_schema.fk_parent (id);
SELECT count(*) FROM pg_constraint c JOIN pg_namespace n ON n.oid = c.connamespace WHERE n.nspname = 'syntax_schema_name' AND c.conname = 'fk_good' AND c.contype = 'f';

选定的 18.6 与 10.21 运行均通过 SQLSTATE、严重级别、状态/恢复、修复、清理和一次性实例停止断言。详见 案例 JSON 与 作者证据；私有清单和注册表哈希也记录在其中。

版本 {#versions}

锁定目录从 7.4 存在边界起包含该条件并列出相关快照。选定自然案例已在 PostgreSQL 18.6 与 10.21 通过；这是有界观察，不能推断所有中间版本或所有源码分支。
