postgresql csv import pdo

Readers,

Forgive the simplicity, but having problems to start:

<?php
	try {
		$dbconnect = new PDO(pgsql:host=localhost; dbname=cpacweb; user=someuser; password=somepassword);
		}
	catch(PDOException $e) {
		print "Error!: " . $e->getMessage() . "<br/>";
		die();
		}

	$query = "SELECT * FROM somedata";
	$result = pg_exec($dbconnect, $query);
	echo "Number of rows: " . pg_numrows($result);
	pg_freeresult($result);
	pg_close($dbconnect);
?>

No error message, no print of rows of table. Please what is the error?
