ALTER GROUP(7)		PostgreSQL 9.6.3 Documentation		ALTER GROUP(7)

NAME
       ALTER_GROUP - change role name or membership

SYNOPSIS
       ALTER GROUP role_specification ADD USER user_name [, ...	]
       ALTER GROUP role_specification DROP USER	user_name [, ... ]

       where role_specification	can be:

	   role_name
	 | CURRENT_USER
	 | SESSION_USER

       ALTER GROUP group_name RENAME TO	new_name

DESCRIPTION
       ALTER GROUP changes the attributes of a user group. This	is an obsolete
       command,	though still accepted for backwards compatibility, because
       groups (and users too) have been	superseded by the more general concept
       of roles.

       The first two variants add users	to a group or remove them from a
       group. (Any role	can play the part of either a "user" or	a "group" for
       this purpose.) These variants are effectively equivalent	to granting or
       revoking	membership in the role named as	the "group"; so	the preferred
       way to do this is to use	GRANT(7) or REVOKE(7).

       The third variant changes the name of the group.	This is	exactly
       equivalent to renaming the role with ALTER ROLE (ALTER_ROLE(7)).

PARAMETERS
       group_name
	   The name of the group (role)	to modify.

       user_name
	   Users (roles) that are to be	added to or removed from the group.
	   The users must already exist; ALTER GROUP does not create or	drop
	   users.

       new_name
	   The new name	of the group.

EXAMPLES
       Add users to a group:

	   ALTER GROUP staff ADD USER karl, john;

       Remove a	user from a group:

	   ALTER GROUP workers DROP USER beth;

COMPATIBILITY
       There is	no ALTER GROUP statement in the	SQL standard.

SEE ALSO
       GRANT(7), REVOKE(7), ALTER ROLE (ALTER_ROLE(7))
