Example #1 pg_update() example
<?php
$db = pg_connect('dbname=foo');
$data = array('field1'=>'AA', 'field2'=>'BB');
// This is safe, since $_POST is converted automatically
$res = pg_update($db, 'post_log', $_POST, $data);
if ($res) {
echo "Data is updated: $res\n";
} else {
echo "User must have sent wrong inputs\n";
}
