setting contrib lo visible to all schemas

hello I`m trying to restore a database that uses contrib type lo. The
database uses one schema where the relations are created
before restoring the schema I execute the command

psql -d dbname -f path-to-contrib/lo.sql

after this I restore the schema and then the data of the database

the problems comes up when trying to make an update to the database schema
from a delphi application
the table has a column of type lo and when trying to update the table I got
the error saying
that lo type does not exist.

I guess this is because when executing the sql command to install lo, it
makes it visible from the public schema only
not from the schema I`m using. So my question is how can I make lo type to
be visible from all schemas

by visible I mean accesible: not need to use for example public.lo to define
a field of type lo

thanks in advanced
