# REASSIGN OWNED

## Name

REASSIGN OWNED -- change the ownership of database objects owned by a database role

## Synopsis

    REASSIGN OWNED BY { old_role | CURRENT_USER | SESSION_USER } [, ...]
                   TO { new_role | CURRENT_USER | SESSION_USER }

## Description

`REASSIGN OWNED` instructs the system to change the ownership of database objects owned by any of the `old_roles` to `new_role`.

## Parameters

`old_role`

  The name of a role. The ownership of all the objects within the current database, and of all shared objects (databases, tablespaces), owned by this role will be reassigned to `new_role`.

`new_role`

  The name of the role that will be made the new owner of the affected objects.

## Notes

`REASSIGN OWNED` is often used to prepare for the removal of one or more roles. Because `REASSIGN OWNED` does not affect objects within other databases, it is usually necessary to execute this command in each database that contains objects owned by a role that is to be removed.

`REASSIGN OWNED` requires privileges on both the source role(s) and the target role.

The DROP OWNED command is an alternative that simply drops all the database objects owned by one or more roles.

The `REASSIGN OWNED` command does not affect any privileges granted to the `old_roles` for objects that are not owned by them. Use `DROP OWNED` to revoke such privileges.

See Section 21.4 for more discussion.

## Compatibility

The `REASSIGN OWNED` command is a PostgreSQL extension.
