Hi Team,

In my database Autovacuum is enabled and sets the below updated value in the Autovacuum related parameter. Here my question is after performing Autovacuum on a daily basis the below value is coming in n_dead_tup. If I will manually Autovacuum then it's fine.

Can someone help me to solve my request? The below current parameter setting updated
 
databaseName=# show autovacuum;
 autovacuum
------------
 on
(1 row)

databaseName=# show autovacuum_vacuum_threshold;
 autovacuum_vacuum_threshold
-----------------------------
 50
(1 row)

databaseName=# show autovacuum_vacuum_scale_factor;
 autovacuum_vacuum_scale_factor
--------------------------------
 0.2
(1 row)

databaseName=# show autovacuum_vacuum_cost_delay;
 autovacuum_vacuum_cost_delay
------------------------------
 2ms
(1 row)

databaseName=#



databaseName=# /
          tblnam          | n_dead_tup |  pfrag
--------------------------+------------+---------
   applicationusername.tablename1 |      52625 | 5262500
