set_session_authorization ::= SET [ SESSION | LOCAL ] SESSION 
                              AUTHORIZATION { role_name | DEFAULT }

reset_session_authorization ::= RESET SESSION AUTHORIZATION

set_session_authorization

reset_session_authorization

Semantics

Session user can only be changed by superusers. Once the session user is set to role_name, any further SQL commands will use the privileges available to that role.

To reset the session user back to current authenticated user, RESET SESSION AUTHORIZATION or SET SESSION AUTHORIZATION DEFAULT can be used.

Examples

Set session user to John.

yugabyte=# select session_user, current_user;
 session_user | current_user
--------------+--------------
 yugabyte     | yugabyte
(1 row)
yugabyte=# set session authorization john;
SET
yugabyte=# select session_user, current_user;
 session_user | current_user
--------------+--------------
 john     | john
(1 row)
