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

["JEAN-PIERRE PELLETIER" <pelletier_32(at)sympatico(dot)ca>]

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
