Use the *Materialized View* dialog to define a materialized view. A materialized view is a stored or cached view that contains the result set of a query. Use the REFRESH MATERIALIZED VIEW command to update the content of a materialized view.
The *Materialized View* dialog organizes the development of a materialized_view through the following dialog tabs: *General*, *Definition*, *Security*, and *Storage*. The *SQL* tab displays the SQL code generated by dialog selections.

Use the fields in the *General* tab to identify the materialized view:
* Use the *Name* field to add a descriptive name for the materialized view. The name will be displayed in the *pgAdmin* tree control.
* Use the drop-down listbox next to *Owner* to select a role.
* Use the drop-down listbox next to *Owner* to select the role that will own the materialized view.
* Select the name of the schema in which the materialized view will reside from the drop-down listbox in the *Schema* field.
* Store notes about the materialized view in the *Comment* field.

Use the fields in the *Storage* tab to maintain the materialized view:
* Move the *With Data* switch to the *Yes* position to specify the materialized view should be populated at creation time. If not, the materialized view cannot be queried until you invoke REFRESH MATERIALIZED VIEW.
* Use the drop-down listbox next to *Tablespace* to select a location for the materialized view.
* Use the *Fill Factor* field to specify a fill factor for the materialized view. The fill factor for a table is a percentage between 10 and 100. 100 (complete packing) is the default.
Click the *Parameter* tab to continue.

Use the tabs nested inside the *Parameter* tab to specify VACUUM and ANALYZE thresholds; use the *Table* tab and the *Toast Table* tab to customize values for the table and the associated toast table. To change the default values:
* Move the *Custom auto-vacuum?* switch to the *Yes* position to perform custom maintenance on the materialized view.
