You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: register.go
    path of file: ./repos/postgres-operator/pkg/apis/acid.zalan.do/v1
    
    the code of the file until where you have to start completion: package v1

import (
	acidzalando "github.com/zalan
    
func addKnownTypes(scheme *runtime.Scheme) error {
	// AddKnownType assumes derives the type kind from the type name, which is always uppercase.
	// For our CRDs we use lowercase names historically, therefore we have to supply the name separately.
	// TODO: User uppercase CRDResourceKind of our types in the next major API version
	scheme.AddKnownTypeWithName(SchemeGroupVersion.WithKind("postgresql"), &Postgresql{})
