AWX DB size not decreasing

Hello Folks,

Upgraded our AWX 15.0.1 to 23.9.0.
It was a fresh install with DB migrated separately.

After cleaning up lots of data, the size of DB isn’t decreasing.
See both autovacuum & track_counts are on.

psql -U awx
psql (13.14 (Debian 13.14-1.pgdg120+2))
Type “help” for help.

awx=#
awx=# show autovacuum;
autovacuum

on
(1 row)

awx=# show track_counts;
track_counts

on
(1 row)

Manually changed these settings in “postgresql.conf” as well and restarted AWX.
DB size still remains same even after a week.

Request assistance to figure out the anomaly.
