How to fix it?

Answer 1

kubectl create -f 
https://operatorhub.io/install/postgresql-operator-dev4devs-com.yamlkubectl 
create -f 
https://operatorhub.io/install/postgresql-operator-dev4devs-com.yaml

duplicate create -f, so you need use only create -f as:

kubectl create -f 
https://operatorhub.io/install/postgresql-operator-dev4devs-com.yaml 
https://operatorhub.io/install/postgresql-operator-dev4devs-com.yaml
