Didn't seem likely, to be honest.

What happens if you try the query as a cursor, perhaps with an order-by 
on customer_id or something to encourage index use? Do you ever get a 
first row back?

In fact, what happens if you slap an index over all your join columns on 
xsegment_dim? With 7,000 rows that should make it a cheap test.
