Hi David,

First of all, thanks for your great work. As you maybe already know, Dibi is our historical ORM for the Pydio project, and we love it: doing the job efficiently, and very lightweight (we embed the minified version).
I'm not totally sure this is an issue, or maybe a postgre config or version problem, I must admit I'm not a PG expert. We are encountering an issue with LIKE queries containing an underscore, and I happened to fix this by changing the escapeLike function of the PG driver to replace '' by _ instead of \ .
Which gives for the escapeLike function

function escapeLike($value,$pos){
    $value=pg_escape_string($this->connection,$value);
    $value=strtr($value,array('%'=>'\\%','_'=>'\\_'));
    return($pos<=0?"'%":"'").$value.($pos>=0?"%'":"'");
}

Do you know if it's a bug or something wrong on my -db- side?
Using PG 9.3 BTW.

Cheers
Charles
