This is my first time out with pg_lo* functions

configure line
./configure  --with-apache=/usr/src/inspire/apache_1.3.12 --enable-track-vars --enable-magic-quotes --with-pgsql --with-mysql=/usr/local/mysql --with-sybase=/opt/sybase

Relevant output:
checking for PostgresSQL support... yes
checking for PQcmdTuples in -lpq... yes
checking for PQoidValue in -lpq... no

Script (this is from an example. Also tried pg_loreadall() after sending image header but no go:
<?php
$fhandle = pg_loopen($db,$photo,"r");
$img1 = pg_loreadall($fhandle);
$size = pg_loread($fhandle);
header("Content-type: image/jpg");
header("Content-length: $size");
echo $img1;
?>

Output from a backtrace:
Program received signal SIGSEGV, Segmentation fault.
