createPosgraphileSchema() generates schema based on pg role or not? Also seems additional mutations are generated other than pg sql functions that created
Just started building app on node.js and express, have some doubts about the usage of createPosgraphileSchema():

1. the schema options seems not working properly, it always scan the entire db as what I can see from the output json file
2. does the graphql schema generation related to the pgDefaultRole? I have put different db role, but seems getting same schema?
3. Upon checking the mutations, I see more than expected using below, not sure if thats normal behaviour
{
  __schema {
    mutationType {
      fields {
        name
      }
    }
  }
}

Thanks in advance if anyone has experienced similar or has got solution on above.
