max_expr_depth

I recently tried to do a big update with postgres 7.1.2.  The update was
something like
UPDATE table SET status = 2 WHERE id IN (a few thousand entries)  AND
status = 1;


and I got:
ERROR:  Expression too complex: nesting depth exceeds max_expr_depth =
10000

What exactly caused this and how do I work around it?
