*************************
|
|
|
|
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.

|
|
:align: center
|
|
|
|
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.
|
|
