I did try the patch.  It fails just the same way.

With or without the patch, with both 8.2 and 8.3, the 0xffffff00
gets passed from seg_same end ends up atleast in ExecutePlan():
ExecutePlan (estate=0xc1c468, planstate=0xc1c698, operation=CMD_SELECT,   numberTuples=0,
direction=ForwardScanDirection,dest=0xc03250)   at execMain.c:1239
 
1239                    if (TupIsNull(planSlot))
(gdb) p /x planSlot->tts_values[0]
$4 = 0xffffff00

From there on I have no idea what happens with it, but 8.2 turns it
a true, 8.3 into a false.
