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,

Fixed --- thanks for the report! (This didn't make beta2, but will
be in the next one.)

This is just to confirm that 8.2 beta3 fixes that problem.

Thanks again,
