Description:
------------
The simple query like

SELECT attribute7
FROM spot2d.client_tt
WHERE
attribute7 IN (list of values)

which doesn't not contain any placeholders give error 

PDO::query(): SQLSTATE[HY093]: Invalid parameter number: mixed named and positional parameters

While PostgreSQL run this query without any errors


root@spot2dtest:/home/young# psql -h pgdev.spot2d.com -U dev ddc_scj < 2.sql 
Password for user dev: 
 attribute7 
------------
(0 rows)


If you will remove 10-20 values from any place of the list or some symbols (like ? in the middle of string) - it works

all strings quoted with PDO::quote

table content doesn't matter and it can even no exist

Here is the 2.sql file:
https://www.dropbox.com/s/v9lqzk8ht2de5x5/2.sql?dl=0

i wasn't able to reduce size of the file - if you remove 10+ values from beginning or end of list it works

Test script:
---------------
<?php

$dbh = new PDO('pgsql:host=pgdev.spot2d.com;dbname=ddc_scj', 'login_here', 'pass_here');

$sql = file_get_contents("2.sql");
$dbh->query($sql);
