Object visibility for users - user can see all objects

Question

Hi  
  
When I create a user by simply running  
  
create user my_test_user password 'abc123';  
  
this user can see all the objects in all schemas automatically. No other grant commands were issued. By seeing I mean the user can see the table and column names (i.e. metadata). Of course, the user cannot do 'select * from table' for example. There, a message comes saying "permission denied".  
  
This behaviour was observed before:  
- https://forums.aws.amazon.com/thread.jspa?messageID=786121  
- https://forums.aws.amazon.com/thread.jspa?messageID=435219  
without any solution.  
  
Is there still no way to restrict the visibility of the objects to specific users? At least I have not seen anything in the documentation.

Hi MarcelZ,  
  
What you see is correct database table visibility is not controlled by GRANT statements.  This is something Redshift inherits from PostgreSQL and is characteristic of all PostgreSQL derived database engines.     
  
Here's another more recent forum thread where I commented on the same kind of ask:

I hope this helps explain the Redshift behavior you see.  
  
Regards,

Hi klarson  
  
Thanks for your info. Ok, so this is the expected behaviour inherited from PostgreSQL. I think one of the earlier posts was mentioning this as well. I wanted to check if this is still the default behaviour.  
  
Thanks again for your help!  
  
Regards, Marcel
