Re: Bug #883: explain analyze causes postgres to die

I included the code in the "example code" box.  I'll include it again here.
If you need more info, just let me know.

I execute the command:
EXPLAIN ANALYZE INSERT INTO stubs(id, stub_id, nodecount, platform_id,
return_count)
SELECT I.id, A.stub_id, L.nodecount, P.platform_id, count(*)
        FROM logdata L, id_lookup I, all_stubs A, platform P
        WHERE lower(L.email) = lower(I.email)
        AND L.stub_marks = A.stub_marks
        AND L.os_type = P.os_type
        AND L.cpu_type = P.cpu_type
        AND L.version = P.version
        GROUP BY I.id, A.stub_id, L.nodecount, P.platform_id;

and get back(from psql):
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset

The log shows:
