We could probably use RwLock if there's ever contention here, but there shouldn't be for now. This basically looks fine to me. Thanks.

I don't think it matters in practice, and this version is more amenable to us later threadpooling the IO if it gets truly dreadful, but we could alternatively use https://doc.rust-lang.org/stable/std/macro.thread_local.html to defeat the borrow-checker's concerns.

I'm down to try, I've never used thread_locals before.

It's probably better to take a lock for the duration of a hashmap read than to have a thread do IO we've already done on another thread.

Yeah, I think this is fine here, I was only noting the alternate implementation choice because of my pedagogic compulsion.

This is the final release of v0.10.0. Thanks everyone for the beta
testing, pull requests, issues, and patience.

As always, install `cargo-pgrx` with `cargo install cargo-pgrx --locked`
and update your extension Cargo.toml files to use the `0.10.0` pgrx
dependencies.

This release includes support for Postgres 16RC1. Support for the
previous betas has been removed. As such, a fresh `cargo pgrx init` is
required.
