Hi Eric,

What about setting your SQL text to use $1 and $2 as the parameter 
values?  I'm currently doing this in the C API (as I type this!) so not 
sure if this will work in PHP PDO.

$stmt = $db->prepare("SELECT is_password_expired($1::integer, 

When you say "this completely fails" - in what respect?  What errors do 
you get?  Also have you tried making sure your PHP $userId is an integer 
not a string - e.g. settype($userId, 'integer');  Again I'm not sure if 
this has a bearing on the PDO stuff as I've never used it.
