deleting postgresql operator for a single namespace

[Masber]

Dear Zalando postgresql operator community,
We have a k8s cluster which has the zalando postgres operator on multiple namespaces.
I would like to delete the postgres database in one of the namespaces, I tried deleting the statefulset but it got recreated.
My next step would be to run this:

kubectl -n users delete postgresql

I would like to ask for confirmation that running the command above will delete/clean all the k8s objects related to postgresql in ns1 but the other zalando postgresql operators in other namespaces won't be affected.

The reason I ask is because I have not used operators before and I would like to have a better understanding on how this one works

kind regards
