[Comm] undefined function: pg_prepare

[Ilis]

Не могу понять, pg_connect отрабатывает, а
pg_prepare/pg_execute/pg_version undefined

[ilis на altus ~]$ rpm -qa | grep php
php-4.4.8-alt1
apache-mod_php-4.4.8-alt1.1
php-base-2.2-alt1
php-suhosin-0.9.22-alt1
php-pgsql-4.4.8-alt1
php-libs-4.4.8-alt1

В index.php:

print phpinfo(INFO_MODULES);
print "before connect<p />\n";
$pg_conn_string = "dbname=ha user=user password=pass";
$pg_conn = pg_connect($pg_conn_string);
if (!$pg_conn) {
        print "Ошибка подключения!";
        die;
}
print "after pg connect<p />\n";

var_dump($pg_conn);
print "after connect<p />\n";

//$stmt = OCIParse($conn, "alter session set
NLS_DATE_FORMAT='YYYY-MM-DD HH24:MI:SS'");
//OCIExecute($stmt,OCI_DEFAULT);

//$v = pg_version($pg_conn);
//var_dump($v);

$sqlsel="select now() as datum from dual"."\n";
$pg_result = pg_prepare($pg_conn, "datum", $sqlsel);
$pg_result = pg_execute($pg_conn, "datum");

Результат:

PostgreSQL Support	enabled
PostgreSQL(libpq) Version 	8.2.5

before connect

after pg connect

resource(2) of type (pgsql link)

after connect

Fatal error: Call to undefined function: pg_prepare() in
/var/www/.../index.php on line 41

Куда ещё надо смотреть?
