NAME

       DROP ROLE - remove a database role

SYNOPSIS

       DROP ROLE [ IF EXISTS ] name [, ...]

DESCRIPTION

       DROP ROLE removes the specified role(s).  To drop a superuser role, you
       must be a superuser yourself; to drop  non-superuser  roles,  you  must
       have CREATEROLE privilege.

       A  role  cannot be removed if it is still referenced in any database of
       the cluster; an error will be raised if so. Before dropping  the  role,
       you must drop all the objects it owns (or reassign their ownership) and
       revoke any privileges the role has been  granted.  The  REASSIGN  OWNED
       [reassign_owned(7)]  and  DROP  OWNED  [drop_owned(7)]  commands can be
       useful for this purpose.

       However, it is not necessary to remove role memberships  involving  the
       role;  DROP  ROLE  automatically  revokes any memberships of the target
       role in other roles, and of other roles in the target role.  The  other
       roles are not dropped nor otherwise affected.

PARAMETERS

       IF EXISTS
              Do  not  throw  an error if the role does not exist. A notice is
              issued in this case.

       name   The name of the role to remove.

NOTES

       PostgreSQL includes a program dropuser [dropuser(1)] that has the  same
       functionality  as this command (in fact, it calls this command) but can
       be run from the command shell.

EXAMPLES

       To drop a role:

       DROP ROLE jonathan;

COMPATIBILITY

       The SQL standard defines DROP ROLE, but it allows only one role  to  be
       dropped  at  a  time, and it specifies different privilege requirements
       than PostgreSQL uses.
