It works for me:

regression=# EXPLAIN ANALYZE SELECT 'foo' FROM foo WHERE id = 0;
                                                 QUERY PLAN
------------------------------------------------------------------------------------------------------------
 Index Scan using foo_pk on foo  (cost=0.00..4.82 rows=1 width=0) (actual time=0.241..0.241 rows=0 loops=1)
   Index Cond: (id = 0)
 Total runtime: 0.456 ms
(3 rows)

I don't think you're really testing 8.1.  Try "select version()"
