lo_import problems

Hi,
   I'm trying to write an script in Perl5 that do an lo_import, but
using the one that the perl interface offers returns an oid equal to
zero:

...
$conn = Pg::connectdb("dbname=test");
$lobjId = $conn->lo_import($file);
...
   Where $file is the file to be imported into the database. If I try to do as in Chapter 45:

INSERT INTO image (name, raster) VALUES ('beautiful image', lo_import('/etc/motd'));
   I get the following error:

ERROR:  You must have Postgres superuser privilege to use server-side lo_import().       Anyone can use the client-side
lo_import()provided by libpq.
 
   And, indeed, this only works when logged on as superuser on the database, but not with the others.

Thanks in advance.
