I'm still not having any luck reproducing the failure here.  Grasping at
straws again, I wonder if it's got something to do with the order in
which the planner examines the indexes --- which is OID order.  Could
you send me the results of

select indexrelid::regclass from pg_index where indrelid = 'detail_summary'::regclass order by indexrelid;
