rust-postgres support library for the r2d2 connection pool.
```rust extern crate r2d2; extern crate r2d2_postgres; extern crate postgres;
use std::thread; use postgres::SslMode; use r2d2_postgres::PostgresConnectionManager;
fn main() { let config = r2d2::Config::default(); let manager = PostgresConnectionManager::new("postgres://postgres@localhost", SslMode::None).unwrap(); let pool = r2d2::Pool::new(config, manager).unwrap();
for i in 0..10i32 {
let pool = pool.clone();
thread::spawn(move || {
let conn = pool.get().unwrap();
conn.execute("INSERT INTO foo (bar) VALUES ($1)", &[&i]).unwrap();
});
}
} ```
