Description:
------------
When using the same binding id in a query the PDOStatement::execute() method still requires you to specify the same amount of parameters.

Reproduce code:
---------------
<?php
$pdo = new PDO('pgsql:host=localhost dbname=bats user=user password=pass');
$pdo->setAttribute(PDO_ATTR_ERRMODE, PDO_ERRMODE_EXCEPTION);

$statement = $pdo->prepare("
            UPDATE groups
            SET
               lft = CASE WHEN lft > :right
                     THEN lft + 2
                     ELSE lft END,
               rgt = CASE WHEN rgt >= :right
                     THEN rgt + 2
                     ELSE rgt END
            WHERE
              rgt >= :right
            ");
$statement->execute(array(':right' => 5));

?>

Expected result:
----------------
Would expect the statement to execute without issue.

Actual result:
--------------
PHP Fatal error:  Uncaught exception 'PDOException' with message 'SQLSTATE[08P01]: <<Unknown error>>: 7 ERROR:  bind message supplies 1 parameters, but prepared statement "pdo_pgsql_stmt_08257c0c" requires 3' in /usr/home/wb/bats/scripts/tests/pdoQuery.php:17

It's not portable to rely on that.
You need to create three parameters and bind them separately.

Fair enougth.

I will submit a note to the php manual about this.

Keep up the good work :)

Use of named placeholders is also not portable, as MySQL supports only positional placeholders, yet PDO emulates it. Why does PDO emulate named placeholders on MySQL but not emulate repeated placeholders? Otherwise, applications using PDO will end up littered with passive-aggressive workarounds:

  $args[':skuid_bug33886'] = $args[':skuid'];
  $args[':supplierid_bug33886'] = $args[':supplierid'];

Would

$statement = $pdo->prepare("
    SET @sql_param=:php_param;
    SELECT ... FROM TAB where p=@sql_param or q=@sql_param
");
$statement->execute(array(':php_param' => $php_variable));


work?
