I think what is happening is that dbuser is not a superuser (correct?)
and therefore is unable to disable triggers during the restore.  But
you have to disable the lo_manage trigger to avoid errors, because
lo_manage will think it has to clean up the blob references in the
existing data.

In short: if you are using the LO type then blob restores have to be
done as superuser.  I suppose this oughta be documented someplace...
