> Ok, I really like the approach Rust is taking and appreciate their effort to make low-level system programming safer, but it really is getting ridiculous. Not that implementing a DB system in Rust would be infeasible, but advocating to just rewrite some large projects in Rust is probably not the step forward.

Note that the OP has, afaik, no involvement in the rust project. Nor has he done much hacking on postgres. Don't think the rust people can be blamed for that one.
