Postgres + Rust is one of the most exciting intersections of tech I've seen in a while.

There's external tooling like his project, but postgres extensions in Rust are exciting.

Full extensions via pgrx have been cool to see, but plrust + pg_tle is also starting to show up.

If you aren't familiar with TLE (Trusted Language Extensions), it is a postgres extension from AWS that created some privileged interfaces for procedural languages (used for user-defined functions) to do some extra stuff. Right now it's mostly auth-related hooks but my hope is that it expands in the future.

Plrust is a procedural language extension for Rust, allowing user defined functions written in Rust.

The combination of those two could open up a world of rich extensions usable in managed hosted environments like RDS.
