啟用協程Postgresql客戶端
----
* 需要在編譯`swoole`時增加`./configure --enable-coroutine-postgresql` 來開啟此功能
* 需要確保系統中已安裝`libpq`庫 
* mac安裝完`postgresq`自帶`libpq`庫，環境之間有差異，`ubuntu`可能需要`apt-get install libpq-dev` 
* 也可以單獨指定libpq庫目錄如：`./configure --enable-coroutine-postgresql --with-libpq-dir=/etc/postgresql`

使用示例
---
```php
go(function () {
    $pg = new Swoole\Coroutine\PostgreSQL();
    $conn  = $pg -> connect ("host=127.0.0.1 port=5432 dbname=test user=root password=");
    $result = $pg -> query($conn, 'SELECT * FROM test;');
    $arr = $pg -> fetchAll($result);
    var_dump($arr);
});
```
