Problem with Large Object Interface of pgsql_perl5

I'm using PostgreSQL 6.5.3, Perl 5.005_03, and pgsql_perl5 1.8.0 on
Linux (intel).

Running this program:

#!/usr/bin/perl
use strict;
package Main;

use Pg;

my $db_name='excised';
my $db_user='excised';
my $db_passwd='excised';

# Connect to the database server
my $dbconn = Pg::connectdb("dbname=$db_name user=$db_user
password=$db_passwd");
if($dbconn->status ne PGRES_CONNECTION_OK){
# We failed to get a connection, exit with error  my $error=$dbconn->errorMessage;  print "Error on connection:
$error\n"; exit;
 
}

print "Database connection opened\n";

my $newoid = $dbconn->lo_creat(PGRES_INV_WRITE|PGRES_INV_READ);

if($newoid == PGRES_InvalidOid){  my $error = $dbconn->errorMessage;  print "Error on lo_creat: $error\n";  exit;
}

print "LO created\n";

my $fd = $dbconn->lo_open($newoid,PGRES_INV_WRITE);

if($fd == -1){
# Error on opening new oid  my $error = $dbconn->errorMessage;  print "Error on lo_open (oid = $newoid): $error\n";  #
Tryto unlink the oid  $dbconn->lo_unlink($newoid);  exit;
 
}

print "LO opened\n";

my $content = 'This is a test of the emergency broadcasting system, in the
event of a real emergency...';

my $numbytes=$dbconn->lo_write($fd,$content,length($content));

if($numbytes != length($content)){  my $rightnum=length($content);  my $error = $dbconn->errorMessage;  print "Error on
lo_write($numbytes != $rightnum): $error\n";  # Try to unlink the oid  $dbconn->lo_close($fd);
$dbconn->lo_unlink($newoid); exit;
 
}

print "LO written\n";

$dbconn->lo_close($fd);

$dbconn->lo_unlink($newoid);


I get this output:

Database connection opened
LO created
Error on lo_open (oid = 46401): ERROR:  lo_lseek: invalid large obj
descriptor (0)

Can anyone tell me what I'm doing wrong?

All help is greatly appreciated.
