postgresql – Empty table TOAST

Is it possible to obtain the number of dead / live tuples for the TOAST table as we do for the normal table?

CREATE TABLE messages1 (message text);

Insert in messages1
SELECT (SELECT
string_agg (chr (floor (random () * 26) :: int + 65), & # 39; & # 39;)
DE genera_series (1,10000))
FROM generate_series (1,10);

SELECT reltoastrelid :: regclass
FROM pg_class
WHERE relname = & # 39; messages1 & # 39 ;;

DELETE FROM messages1
Where is it located
SELECT ctid
FROM messages1
ORDER BY 1
LIMIT 6
);

postgres = # SELECT reltoastrelid :: regclass
postgres- # FROM pg_class
postgres- # WHERE relname = & # 39; messages1 & # 39 ;;
Reltoastrelid
----------------------------
pg_toast.pg_toast_147777
(1 row)


postgres = # select relname, vacuum_count, n_tup_del, n_live_tup, n_dead_tup from pg_stat_user_tables where relname = & # 39; pg_toast.pg_toast_147777 & # 39 ;;
first name vacuum_count | n_tup_del | n_live_tup | n_dead_tup
