ERROR: there is no parameter $1

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']),
util_clean_str($post['middle_name']),
util_clean_str($post['last_name']),
$post['ss_num'],
$post['ref_language_id'],
$post['ref_gender_type_id'],
$post['ref_race_type_id'],
util_clean_str($post['address1']),
util_clean_str($post['address2']),
util_clean_str($post['city']),
$post['ref_state_id'],
util_clean_str($post['postal_code']),
util_clean_str($post['email']),
util_clean_str($post['phone1']),
$post['ref_phone1_type_id'],
util_clean_str($post['phone2']),
$post['ref_phone2_type_id'],
util_clean_str($post['phone3']),
$post['ref_phone3_type_id'],
util_clean_str($post['alias_name']),
$post['dob'],
$post['mr_num'],
$post['ehris_num'],
$post['medicaid_num'],
$post['other_num'],
$post['is_shelter_resident'],
$post['is_icm'],
util_clean_str($post['comments']),
$post['caseworker_id']));

// debug('insert', $sql);

$result = pg_query($trms->db, $sql);

if ($result === false) {
return array(null, "New patient insert failed.<br>" .
pg_last_error($trms->db));
}

$patient_id = pg_fetch_result($result, 0, 0);

return array($patient_id, "Patient insert succeeded.");
