@5150cec1 @c8c5c50e EdgeDB is running on Postgres’ engine, but with a (dramatically better, IMO) new query language. Even though it was originally written in Python, the devs appear to be writing new bits in Rust, and from their public discussions about it, have plans to  gradually rewrite a lot of their implementation in Rust over time. I think the Postgres engine itself will stay untouched for a long time, given the scale of effort required.
