[Plugin: PostgreSQL for WordPress (PG4WP)] backslashes cannot be handled properly

centos + apache 2.2.3 + 5.3.3 + wordpress 3.4.2 + pg4wp 1.3.0 + postgresql 9.2

when I post:
c:\1.mp3
it becomes
c:\\1.mp3

I temporarily solved it by adding
$sql = str_replace( ‘\\\\’, ‘\\’, $sql);
in line 473 of driver_pgsql.php, not sure whether there are some side effects
