ALTER GROUP()                    SQL Commands                    ALTER GROUP()



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       have been superseded by the more general concept of roles.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.

SEE ALSO
       GRANT [grant(7)], REVOKE [revoke(l)], ALTER ROLE [alter_role(l)]
