PostgreSQL Extension in C with Rustlang

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.

  1. Prereq : Tested on Ubuntu 18, GCC, postgresql-server-11, postgresql-dev-11, rustlang
  2. Create new project Cargo embed and cd embed
  3. Rename the file src/main.rs to lib.rs
  4. Add following code
#[no_mangle]
pub extern fn double_input(input: i32) -> i32 {
    input * 2

Fix DNS resolution in WSL2
More recent resolution:
1. cd ~/../../etc (go to etc folder in WSL).
2. echo "[network]" | sudo tee wsl.conf (Create wsl.conf file and add the first line).
3. echo "generateResolvConf = false" | sudo tee -a wsl.conf (Append wsl.conf the next line).
4. wsl --terminate Debian (Terminate WSL in Windows cmd, in case is Ubuntu not Debian).
5. cd ~/../../etc (go to etc folder in WSL).
6. sudo rm -Rf resolv.conf (Delete the resolv.conf file).
7. In windows cmd, ps or terminal with the vpn connected do: Get-NetIPInterface or ipconfig /all for get the dns primary and
secondary.
