DROP ROLE(7)                      PostgreSQL 14.15 Documentation                     DROP ROLE(7)

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 on
       other objects. The REASSIGN OWNED and DROP OWNED commands can be useful for this purpose;
       see Section 22.4 for more discussion.

       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(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))
