failed to build any 8-way joins: SQLSTATE: XX000 on PostgreSQL 8.2.6

Hi all, I've seen other mentions of this happening but this instance is 
with a newer server version than the ones that had a patch applied.

Basically, 8 LEFT JOINs, and removing any one of them stop the symptom. 
I'll provide more data if the query in itself doesn't not indicate 
what's causing the problem...
