Forking Postgres and patching the transaction engine to aid granular recovery is one obvious way to achieve this, but the more robust solution is to fork the Linux kernel and apply a surgical patch to the TCP/IP stack. A kernel level regex check on port 5432 traffic prevents Claude from dropping your prod DB tables in the first place.

Wouldn't it be easier to patch gnu c compiler that compiles the kernel? That way anyone compiling kernels will auto include the enhancement by default across all OS, unix or linux.
