The lib I use is call lo_in and lo_out for manage BLOB.

I understand that lo_unlink be related with lo_import and lo_export so I don't think that it work.

Deleting the OID does not remove the object itself - see details of
lo_unlink() in Chapter 28 of the manuals.

I seem to recall some other utilities in the contrib/ directory of the
source distribution too.
