Just a small gist to show how you can easily create a Rust shared lib, wrap it with C and call it from PostgreSQL SQL Command.

0. Prereq : Tested on Ubuntu 18, GCC, postgresql-server-11, postgresql-dev-11, rustlang
1. Create new project Cargo embed and cd embed
2. Rename the file src/main.rs to lib.rs
3. Add following code

#[no_mangle]
pub extern fn double_input(input: i32) -> i32 {
    input * 2

ayourtch

#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#ifdef _MSC_VER
#include <intrin.h> /* for rdtscp and clflush */
#pragma optimize("gt",on)
#else
#include <x86intrin.h> /* for rdtscp and clflush */
#endif
