ERROR: failed to build any 4-way joins SQL state: XX000, PostgreSQL 8.2 beta1

Hi,

I have a query that throws "ERROR: failed to build any 4-way joins
SQL state: XX000".

Here's an (arguably) simplified version of it that doesn't require any of my
table:

select
   1
from
   (select 1 as col) t1

   cross join (select 1 as col) t2

   left outer join (select 1 as col) t3
   on  t1.col = t3.col
   and t2.col = t3.col
   and 1 = t3.col

   left outer join (select 1 as col) t4
   on t3.col = t4.col

I am on PostgreSQL 8.2 beta1 under Windows XP Service Pack 2.

Thanks,
Jean-Pierre Pelletier
