K8SPG-634: Auto schema creation

[inelpandzic]

CHANGE DESCRIPTION

Problem:
Currently when users are created, you can't start using them right away, as they don't have permissions to use public schema. This breaks a lot of declarative flows. We want to automatically create schemas for users defined in spec.users.

Solution:
Utilize Crunchy feature to create schemas automatically by setting postgres-operator.crunchydata.com/autoCreateUserSchema=true annotation.

we don't need here check for operator version?

[inelpandzic]

No, don't think so.
