- Enable roles for individual users on login (either with the SET ROLE command or default roles).
- Enable all roles for all users on login (at the database level via the EnableAllRolesOnLogin parameter).
Example:
dbadmin=> SELECT all_roles, default_roles
dbadmin-> FROM users
dbadmin-> WHERE user_name = 'lucy';
all_roles | default_roles
----------------------------------+---------------
read_all_reports, update_allowed |
(1 row)
dbadmin=> \c - lucy
You are now connected as user "lucy".
dbadmin=> SHOW enabled roles;
name | setting
---------------+---------
enabled roles |
(1 row)
dbadmin=> \c - dbadmin
You are now connected as user "dbadmin".
dbadmin=> SELECT parameter_name, current_value, default_value, allowed_levels, description
dbadmin-> FROM configuration_parameters
dbadmin-> WHERE parameter_name = 'EnableAllRolesOnLogin';
parameter_name | current_value | default_value | allowed_levels | description
-----------------------+---------------+---------------+----------------+-----------------------------------
EnableAllRolesOnLogin | 0 | 0 | DATABASE | Enable all granted roles on login
(1 row)
dbadmin=> ALTER DATABASE test_db SET EnableAllRolesOnLogin = 1;
ALTER DATABASE
dbadmin=> \c - lucy
You are now connected as user "lucy".
dbadmin=> SHOW enabled roles;
name | setting
---------------+----------------------------------
enabled roles | read_all_reports, update_allowed
(1 row)

Vertica Field Chief Technologist
I've had the privilege of working with many database technologies in my career. But after being introduced to Vertica in May of 2011 as a client, I was hooked on the new technology after witnessing a query run in milliseconds that had previously ran for hours on the legacy database we had in place. It was then that I knew I wanted to eventually join the Vertica team, and 4 years later I did! I am currently a Vertica evangelist and am ready to help you get on board! Please feel free to reach out to me with any questions you have about Vertica and make sure to follow my Vertica Quick Tips!
