`Grant Wizard`:index:
*********************

The *Grant Wizard* tool is a graphical interface that allows you to manage the
privileges of one or more database objects in a point-and-click environment. A
search box, dropdown lists, and checkboxes facilitate quick selections of
database objects, roles and privileges.

The wizard organizes privilege management through a sequence of windows:
*Object Selection*, *Privileges Selection* and
*Review Selection*. The *Review Selection* window
displays the SQL code generated by wizard selections.

To launch the *Grant Wizard* tool, select a database object in the *pgAdmin*
tree control, then navigate through *Tools* on the menu bar to click on the
*Grant Wizard* option.

Use the fields in the *Object Selection* window to select the
object or objects on which you are modifying privileges. Use the *Search by
object type or name* field to locate a database object, or use the scrollbar
to scroll through the list of all accessible objects.

* Each row in the table lists object identifiers; check the checkbox in the left
  column to include an object as a target of the Grant Wizard.  The table
  displays:

    * The object type in the *Object Type* field
    * The schema in which the object resides in the *Schema* field
    * The object name in the *Name* field.

Click the *Next* button to continue, or the *X* button to close the wizard
without modifying privileges.

Use the fields in the *Privileges Selection* window to grant
privileges. If you grant a privilege WITH GRANT OPTION, the Grantee will have
the right to grant privileges on the object to others. If WITH GRANT OPTION is
subsequently revoked, any role who received access to that object from that
Grantee (directly or through a chain of grants) will lose their privileges on
the object.

* Click the *Add* icon (+) to assign a set of privileges.
* Select the name of the role from the drop-down listbox in the *Grantee* field.
* Click inside the *Privileges* field. Check the boxes to the left of one or
  more privileges to grant the selected privileges to the specified user. If
  privileges have previously been granted on a database object, unchecking a
  privilege for a group or user will result in revoking that privilege.
* The current user, who is the default grantor for granting the privilege, is displayed in the *Grantor* field.
* Click the *Add* icon (+) to assign a set of privileges to another role; to
  discard a privilege, click the trash icon to the left of the row and confirm
  deletion in the *Delete Row* dialog.

For more information about granting privileges on database objects, see the
`PostgreSQL core documentation <https://www.postgresql.org/docs/current/sql-grant.html>`_.

Click the *Next* button to continue, the *Back* button to select or deselect
additional database objects, or the *X* button to close the wizard without
modifying privileges.

Your entries in the *Grant Wizard* tool generate a SQL command; you can review
the command in the *Review Selection* window (see an
example below).
