ALTER GROUP
ALTER GROUP
Synopsis
ALTER GROUP name ADD USER username [, ... ] ALTER GROUP name DROP USER username [, ... ]
Description
ALTER GROUP is used to add or remove users from a group. Only database superusers can use this command. Adding a user to a group does not create the user. Similarly, removing a user from a group does not drop the user itself.
Use CREATE GROUP to create a new group and DROP GROUP to remove a group.
Usage
Add users to a group:
ALTER GROUP staff ADD USER karl, john;
Remove a user from a group:
ALTER GROUP workers DROP USER beth;
