The Extension Dialog
|
|
********************
|
|
|
|
Use the *Extension* dialog to install a new extension into the current database. An extension is a collection of SQL objects that add targeted functionality to your Postgres installation. The *Extension* dialog adds the functionality of an extension to the current database only; you must register the extension in each database that use the extension. Before you load an extension into a database, you should confirm that any pre-requisite files are installed.
|
|
|
|
The *Extension* dialog allows you to implement options of the CREATE EXTENSION command through the following dialog tabs: *General* and *Definition*. The *SQL* tab displays the SQL code generated by dialog selections.

|
|
|
|
Use the fields in the *General* tab to identify an extension:
|
|
|
|
* Use the drop-down listbox in the *Name* field to select the extension. Each extension must have a unique name.
|
|
* Store notes about the extension in the *Comment* field.
|
|
|
|
Click the *Definition* tab to continue.
|
|
|
|

|
|

|
|
|
|
Use the *Definition* tab to select the *Schema* and *Version*:
|
|
|
|
* Use the drop-down listbox next to *Schema* to select the name of the schema in which to install the extension's objects.
|
|
* Use the drop-down listbox next to *Version* to select the version of the extension to install.
|
|
|
|
Click the *SQL* tab to continue.
|
|
|
|
Your entries in the *Extension* dialog generate a SQL command (see an example below). Use the *SQL* tab for review; revisit or switch tabs to make any changes to the SQL command.
|
|
|
|
**Example**
|
|
|
|
The following is an example of the sql command generated by user selections in the *Extension* dialog:
|
|
|
|
.. image:: images/extension_sql.png
|
|
:alt: Extension dialog sql tab
|
|
|
|
The command creates the *chkpass* extension in the *public* schema. It is version *1.0* of *chkpass*.
