Are you using DBD::Pg in your Perl script? You can use the lo interface
via the func method of the DBI driver:

$lob_fd = $dbh->func($lobId, $mode, "lo_open");

See the perldoc on DBD::Pg for more information on how to do this. The
DBD::pg is built over libpq, so you should be able to export via this
facility.
