Kill `std::panic::set_hook()` and `std::panic::take_hook()`?

It's unclear to me what those mean in the context of plrust, a pgx-based extension that installs its own panic handler, then dynamically loading a user function, also written in rust, that doesn't install its own language handler.

That would break this code:

https://github.com/tcdi/pgx/blob/4b9467aebfd88c71cf0531b76cb524350ef0b698/pgx-pg-sys/src/submodules/panic.rs#L267-L271

That code isn't included in plrust user functions. Only in plrust proper

...hmm. That makes me more worried about how this would work rather than less, but fair.

That should be fine, the cdylib environment is entirely sealed off — it has it's own set of globals and everything. (The panic handler is using hidden symbols so they don't exist outside)
