Could you build this?
No Writing a native PostgreSQL C extension that safely intercepts query execution hooks and assesses runtime lock contention and replication lag requires deep database kernel internals expertise.
What it would actually take: This requires developing a PostgreSQL extension in C using hooks such as `ExecutorStart_hook`, `ProcessUtility_hook`, and `post_parse_analyze_hook`. The extension must safely traverse the SQL AST to detect dangerous patterns and inspect Postgres shared memory (lock tables, WAL sender status, replication delay) with microsecond latency. Ensuring crash safety, zero memory leaks, and high-concurrency stability requires specialized PostgreSQL core systems programming.
