Bug description:PDO query processing with postgres standard_conforming_strings and escape chars

Description:
------------
The test script below shows the point best.

One thing to notice, is that this bug only happens when you have 
standard_conforming_strings set to "on" in your postgres.conf file.

It seems like the fact that PHP uses '\' as escape char might be messing
things 
up, sd $pdo->quote("\\") return '\' when standard_conforming_strings is set
to 
"on" vs, '\\' when it's off.

Test script:
---------------
$pdo = new PDO($dns, $username, $password);
$statement = $pdo->prepare("SELECT table.* FROM table table WHERE (column
ILIKE :db_condition_placeholder_0 ESCAPE " . $pdo->quote("\\") . ") AND
(column ILIKE :db_condition_placeholder_1 ESCAPE " . $pdo->quote("\\") .
");");
$statement->execute(array(':db_condition_placeholder_0' => 'test',
':db_condition_placeholder_1' => 'test'));

Expected result:
----------------
No errors and query executed:

Actual result:
--------------
Error produced: Warning: PDOStatement::execute(): SQLSTATE[HY093]: Invalid

parameter number: :db_condition_placeholder_1 in
