RelStorage shared blobs packing

Hi,

I'm currently working on a Pyramid/ZODB based application using RelStorage
(release 2.1.0, with Python 3.5 and a PostgreSQL database).
Blobs are stored on the filesystem using a shared blobs directory.

Here is my configuration file:

%import relstorage

<zodb>
>     <relstorage>
>         keep-history false
>         blob-dir /var/local/env/website/var/db/blobs
>         shared-blob-dir yes
>         <postgresql>
>             dsn host='xxx' port='5432' dbname='xxx' user='xxx' password='
> xxx'
>         </postgresql>
>     </relstorage>
>     cache-size 100000
> </zodb>


Storage is configured without keeping history, but blobs are not removed
from filesystem when an object is deleted, or when packing the database!

So my question is simple: how can I remove unused blobs from filesystem?

Best regards,
Thierry
