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.

SEE ALSO

       CREATE ROLE [create_role(7)], ALTER ROLE [alter_role(7)], SET ROLE [set_role(7)]
