Description:
------------
This is the example from  http://nz2.php.net/manual/en/function.pg-fetch-object.php.

This code always produces a warning on the final row - for example, Warning: pg_fetch_object() [function.pg-fetch-object]: Unable to jump to row 21 on PostgreSQL result index 6 in /etc/apache2/htdocs/php/form_ricerca_result.php on line 59

I think it'd be better for the example to not use $row, and be: 

<?php 

$database = "store";

$db_conn = pg_connect("host=localhost port=5432 dbname=$database");
if (!$db_conn) {
  echo "Failed connecting to postgres database $database\n";
  exit;
}

$qu = pg_query($db_conn, "SELECT * FROM books ORDER BY author");

while ($data = pg_fetch_object($qu)) {
  echo $data->author . " (";
  echo $data->year . "): ";
  echo $data->title . "<br />";
}

pg_free_result($qu);
pg_close($db_conn);

?> 






Reproduce code:
---------------
$row = 0; // postgres needs a row counter 

while ($data = pg_fetch_object($qu, $row)) {
  echo $data->author . " (";
  echo $data->year . "): ";
  echo $data->title . "<br />";
  $row++;
}


Expected result:
----------------
Should only output the rows.

Actual result:
--------------
You get a warning at the end of the loop.
