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

If you are using the contrib/lo library, then README.lo mentions:

associated trigger(s). Also, users may not remember (or know) to
create the triggers.
Could this be the case with your database? There are a couple of other
points in the README.lo that are worth checking too.
