lo_ and SU privs

Under PostgreSQL 7.1.3 (RH Linux 7.1 platform) I get
the following whenever trying to manipulate large
objects either from psql or sql oriented API's (eg.
PoPy, psycopg, pypgsql (DPAPI kit)):

You must have Postgres superuser privilege to use
server-side lo_import.  Anyone can use the client-side
lo_import provided by libpq.

Is there any way to disable this behaviour or to give
a user the priviliges that are being looked for?  This
effectively cripples the vast majority of programmatic
interfaces to PostgreSQL ie. all those that are more
than wrappers around libpq.
