<command>DROP ROLE</command> removes the specified role(s).
|
||
|
To drop a superuser role, you must be a superuser yourself;
|
||
|
to drop non-superuser roles, you must have <literal>CREATEROLE</>
|
||
|
privilege.
|
||
|
</para>
|

|
|
||
|
<para>
|
||
|
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.
|
||
|
</para>
|
||
|
|
||
|
<para>
|
||
|
However, it is not necessary to remove role memberships involving
|
||
|
the role; <command>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.
