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

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