Deleting KONG entities does not delete it from Database

I have a KONG implementation with postgress in kubernetes, where i try to delete routes/services via admin API or delete the ingress ingress via k8s , the corresponding route/Services entry in the database table is not being deleted. I tried to delete it manually too and it does not delete?

However I do not see it when i do a HTTP GET on the services/routes via admin API. I am I missing something here? Appreciate any help on this.
