bloat indicator using n_dead_tup column

[Yambu <hyambu@xxxxxxxxx>]

Hello

I would like to know if the below query can be used as a bloat indicator.

select 

n_dead_tup 
/ (n_live_tup * current_setting('autovacuum_vacuum_scale_factor')::float8 
 + current_setting('autovacuum_vacuum_threshold')::float8) > 1 then true else false end as bloated_indicator

FROM pg_stat_user_tables 

i want to use column n_dead_tup to get an estimate or indicator of impending bloat

regards
