DROP_ROLE - remove a database role
DROP ROLE [ IF EXISTS ] name [, ...]
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.
Do not throw an error if the role does not exist. A notice is
issued in this case.
The name of the role to remove.
PostgreSQL includes a program dropuser(1) that has the same
functionality as this command (in fact, it calls this command) but can
be run from the command shell.
To drop a role:
DROP ROLE jonathan;
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.
CREATE ROLE (CREATE_ROLE(7)), ALTER ROLE (ALTER_ROLE(7)), SET ROLE
