ALTER 
GROUP(7)							   SQL Commands 						    ALTER GROUP(7)

NAME

       ALTER GROUP - change role name or membership

SYNOPSIS

       ALTER GROUP groupname ADD USER username [, ... ]
       ALTER GROUP groupname DROP USER username [, ... ]

       ALTER GROUP groupname RENAME TO newname

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       because groups (and users too) have been superseded by the more general concept of roles.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 [grant(7)] or REVOKE [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

       groupname
	      The name of the group (role) to modify.

       username
	      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.

       newname
	      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.
