Thanks for your answer. With that hint, I was able to understand more  
how things work together and I'm able to use my custom driver without  
any modification in the core.

Currently I do the following in backends.local.php:

---
$backends['sql'] = array (
     'disabled' => false,
     'name' => 'mail',
     'preferred' => '',
     'password policy' => array(
         'minLength' => 8,
         'maxLength' => 128,
         'maxSpace' => 10,
         'minUpper' => 1,
         'minLower' => 1,
         'minNumeric' => 1,
         'minSymbols' => 1
     ),
     'driver' => 'Sqlbcrypt',
     'params' => array(
         'phptype'    => 'pgsql',
         'hostspec'   => 'somehost',
         'username'   => 'horde_pw_change',
         'password'   => 'somepass',
         'database'   => 'mail',
         'table'      => 'email_users',
         'user_col'   => '"alias"||\'@\'||"domain"',
         'pass_col'   => 'password_crypt',
         'show_encryption' => true
     )
);

$params = $backends['sql']['params'];
unset($params['table'], $params['user_col'], $params['pass_col'],  
$params['encryption'], $params['show_encryption']);
$backends['sql']['params']['db'] =  
$GLOBALS['injector']->getInstance('Horde_Core_Factory_Db')->create('passwd',  
$params);
---

Actually I could probably do the 'db' setup already in the sql-backend  
configuration itself, by passing the necessary params already there.  
But I'm going to test that later.
