------------------------------------

             Summary: metastore postgres - remove "GRANT ALL ON SCHEMA public 
TO PUBLIC"
                 Key: HIVE-20565
                 URL: https://issues.apache.org/jira/browse/HIVE-20565
             Project: Hive
          Issue Type: Improvement
            Reporter: Thejas M Nair


hive-schema-4.0.0.postgres.sql  has "GRANT ALL ON SCHEMA public TO PUBLIC"
That grants permissions to all users to create new  create new objects under 
the public schema.
We need to give only hive user permissions on this schema, not public. That 
would be more secure.
