Sure:

-[ RECORD 2 ]----------+------------------------------
schemaname             | public
relname                | general_info
n_dead_tup             | 12
n_live_tup             | 1
n_tup_upd              | 8817
n_tup_del              | 0
n_tup_ins              | 0
n_tup_hot_upd          | 8817
pg_relation_size       | 155648
pg_total_relation_size | 172032
-[ RECORD 4 ]----------+------------------------------
schemaname             | public
relname                | current_info
n_dead_tup             | 27
n_live_tup             | 1
n_tup_upd              | 3296
n_tup_del              | 0
n_tup_ins              | 0
n_tup_hot_upd          | 3296
pg_relation_size       | 385024
pg_total_relation_size | 409600

One question: in 8.3 and earlier, is the FSM used to track dead_rows for
pg_stat_user_tables?
