I would love to hack on some features but I worry somewhat that the C compiler won't give me enough hints that I'm doing something wrong, and the Rust compiler has been excellent at preventing bugs.

You can write Postgres extensions in Rust. And Postgres extensions are really powerful. What kind of features are you interested in?

Undoubtedly, attracting Rust folks to contribute Postgres could be a good things.
Yet some very simple questions arise.
1. Is Rust compatible with Memory Contexts and shared memory constructs of Postgres? With elog error reporting, PG_TRY() and his friends?
2. Does Rust support same set of platforms as Postgres? Quick glance at Build Farm can give an impression of what is supported by Postgres[0].
3. Do we gain anything besides compiler hints? Postgres development is hard due to interference of complex subsystems. It will be even harder if those systems will be implemented in different languages.

Probably, answers to all these questions are obvious to Rust pros. I just think this can be of interest to someone new to Rust (like me).
