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

Permanent WSL DNS Fix (WSL 2.2.1+)

If you're encountering ping github.com failing inside WSL with a Temporary failure in name resolution, you're not alone — this has been a long-standing issue, especially when using VPNs or corporate networks.

This issue is now fixed robustly with DNS tunneling, which preserves dynamic DNS behavior and avoids limitations like WSL’s former hard cap of 3 DNS servers in /etc/resolv.conf.

DNS tunneling is enabled by default in WSL version 2.2.1 and later, meaning that if you're still seeing DNS resolution issues, the first and most effective fix is simply to upgrade WSL. Upgrading WSL updates the WSL platform itself, but does not affect your installed Linux distributions, apps, or files.

To upgrade WSL, follow these steps,
