title: User restriction in vertica
body: <p>I have some public functions in vertica. I want to create a read only user in vertica who can access only the data tables in the defined schema and not from v_catalog(Information_schema) to list all the table names. Is it possible in vertica to create a user who can be restricted to use any system commands but can access the public functions and UDFS and execute only select command in the defined schema.</p>
