致命錯誤：未捕獲錯誤：調用未定義的函數pg_connect（）

Question

從ubuntu服務器調用我的php腳本時出現此錯誤。我已經使用apt get安裝了php5-pgsql，但錯誤仍然存​​在。以下是我的源代碼，請協助。

<?php 

error_reporting(E_ALL); 
ini_set('display_errors', 1); 

$host = "localhost"; 
$port = "5432"; 
$user = "postgres"; 
$pass = "root"; 
$db = "quickbed"; 

$con = pg_connect("host=$host port=$port dbname=$db user=$user password=$pass") or die ("Could not connect to server\n"); 

$query = "select * from tbl_hosts, (select count(*) from tbl_hosts) as cnt order by registration_time"; 
$rs = pg_query($con, $query) or die("Cannot execute query: $query\n"); 

$rows['spaces'] = pg_fetch_all($rs); 

echo json_encode($rows); 
pg_close($con); 

?>

您必須安裝PostgreSQL模塊並啓用它。 ​​
