# Deadpool for PostgreSQL [![Latest Version](https://img.shields.io/crates/v/deadpool-postgres.svg)](https://crates.io/crates/deadpool-postgres)

Deadpool is a dead simple async pool for connections and objects
of any type.

This crate implements a [`deadpool`](https://crates.io/crates/deadpool)
manager for [`tokio-postgres`](https://crates.io/crates/tokio-postgres)
and also provides a `statement` cache by wrapping `tokio_postgres::Client`
and `tokio_postgres::Transaction`.

## Features

| Feature | Description | Extra dependencies | Default |
| ------- | ----------- | ------------------ | ------- |
| `config` | Enable support for [config](https://crates.io/crates/config) crate | `config`, `serde/derive` | yes |

## Example

```rust
use deadpool_postgres::{Config, Manager, Pool};
use tokio_postgres::{NoTls};

#[tokio::main]
async fn main() {
    let mut cfg = Config::from_env("PG").unwrap();
    let pool = cfg.create_pool(NoTls).unwrap();
    for i in 1..10 {
        let mut client = pool.get().await.unwrap();
        let stmt = client.prepare("SELECT 1 + $1").await.unwrap();
        let rows = client.query(&stmt, &[&i]).await.unwrap();
        let value: i32 = rows[0].get(0);
        assert_eq!(value, i + 1);
    }
}
```
