The speaker thinks a Rust rewrite of Postgres is probably feasible and predicts that a single Rust fork could become the leading version if such a rewrite occurs.

“A really classic one could be, say, Postgres is written in Haskell, which is a very unusual language, and it's very hard to maintain. Could it be re-written in Rust now? Yeah, probably it could.”

“And the mechanism, the, the function is still valuable, and probably there'll be... If that happens, there'll be one Rust fork of Postgres, and that will be the winner for that particular category.”
