ERROR: there is no parameter $1 - Mailing list pgsql-general

This one has me stumped.  Does anyone know under which circumstances
this error would be returned by PHP's pg_query_params() even if the
procedure completed without an apparent error?

The procedure and PHP API code haven't changed in weeks.  I started
getting this after I upgraded the database to 8.3.

Here's the PHP call:

     ....

     $sql = 'SELECT insert_patient_person ($1, $2, $3, $4, $5, $6, NULL,
$7, $8, $9,
                                           $10, $11, $12, $13, $14, $15,
$16, $17, $18, $19,
                                           $20, $21, $22, $23, $24, $25,
$26, $27, $28, $29,
                                           ENTITY_INCOMPLETE())';

     $result = pg_query_params($trms->db, $sql, array(
                                 util_clean_str($post['first_name']),
