Crate pg_pool 

Production-grade async connection pool.

Generic over any connection type that implements Poolable. Features: waiter queue with dead-waiter skipping, jittered max-life, health checks on checkout, lifecycle hooks, graceful drain, and metrics.

Example with pg-wired (requires wire feature)

use pg_pool::{ConnPool, ConnPoolConfig, LifecycleHooks};
use pg_pool::wire::WirePoolable;

let mut config = ConnPoolConfig::default();
config.addr = "127.0.0.1:5432".into();
config.user = "postgres".into();
config.password = "postgres".into();
config.database = "mydb".into();

let _pool = ConnPool::<WirePoolable>::new(config, LifecycleHooks::default()).await?;
