Example:

```rust

extern crate r2d2;

extern crate r2d2_odbc;

extern crate odbc;

use std::thread;

use r2d2_odbc::ODBCConnectionManager;

use odbc::*;

fn main() {

    let manager = ODBCConnectionManager::new("DSN=PostgreSQL");

    let pool = r2d2::Pool::new(manager).unwrap();

    let mut children = vec![];

    for i in 0..10i32 {

        let pool = pool.clone();

        children.push(thread::spawn(move || {

            let pool_conn = pool.get().unwrap();

            let conn = pool_conn.raw();

            let stmt = Statement::with_parent(&conn).unwrap();

            if let Data(mut stmt) = stmt.exec_direct("SELECT version()").unwrap() {

                while let Some(mut cursor) = stmt.fetch().unwrap() {

                    if let Some(val) = cursor.get_data::<&str>(1).unwrap() {

                        println!("THREAD {} {}", i, val);

                    }

                }

            }

        }));

    }

    for child in children {
