Description

The first Rust code example, also available under examples/postgres/getting_started_step_1, is using .ok(); to discard the error case of a Result. If ignoring any errors is intentional, that line should be updated from

dotenv().ok();

to

let _ = dotenv();

Otherwise, the .ok() should be replaced by something else (maybe .expect("dotenv setup to be successful")).
