rust-postgres support library for the r2d2 connection pool.
```rust use std::thread; use postgres::{NoTls, Client}; use r2d2_postgres::PostgresConnectionManager;
fn main() { let manager = PostgresConnectionManager::new( "host=localhost user=postgres".parse().unwrap(), NoTls, ); let pool = r2d2::Pool::new(manager).unwrap();
for i in 0..10i32 {
let pool = pool.clone();
thread::spawn(move || {
let mut client = pool.get().unwrap();
client.execute("INSERT INTO foo (bar) VALUES ($1)", &[&i]).unwrap();
});
}
} ```
