************************
|
|
|
|
Use the CREATE LANGUAGE dialog to register a new procedural language.
|
|
|
|
The *Language* dialog organizes the registration of a procedural language
|
|
through the following dialog tabs: *General*, *Definition*, and *Security*.
|
|
The *SQL* tab displays the SQL code generated by dialog selections.
|
|

|
|
:alt: Language dialog general tab
|
|
:align: center
|
|
|
|
Use the fields in the *General* tab to identify a language:
|
|
|
|
* Use the drop-down listbox next to *Name* to select a language script.
|
|
* Use the drop-down listbox next to *Owner* to select a role.
|
|
* Store notes about the language in the *Comment* field.
|
|
|
|
Click the *Definition* tab to continue.
|
|
|
|
.. image:: images/language_definition.png
|
|
:alt: Language dialog definition tab
|
|
:align: center
|
|
|
|
Use the fields in the *Definition* tab to define parameters:
|
|
|
|
* Move the *Trusted?* switch to the *No* position to specify only users with
|
|
PostgreSQL superuser privilege can use this language. The default is *Yes*.
|
|
* When enabled, use the drop-down listbox next to *Handler Function* to select
|
|
the function that will be called to execute the language's functions.
|
|
* When enabled, use the drop-down listbox next to *Inline Function* to select
|
|
the function that will be called to execute an anonymous code block (DO
|
|
command) in this language.
|
|
* When enabled, use the drop-down listbox next to *Validator Function* to
|
|
select the function that will be called when a new function in the language
|
|
is created, to validate the new function.
|
|
|
|
Click the *Security* tab to continue.
|
|
|
|

|
|
:align: center
|
|
|
|
Use the *Security* tab to assign privileges and define security labels.
|
|
|
|
Use the *Privileges* panel to assign privileges to a role. Click the *Add* icon
|
|
(+) to set privileges for database objects:
|
|
|
|
* 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 privilege to the specified user.
|
|
* The current user, who is the default grantor for granting the privilege, is displayed in the *Grantor* field.
|
|
|
|
Click the *Add* icon (+) to assign additional privileges; to discard a
|
|
privilege, click the trash icon to the left of the row and confirm deletion in
|
|
the *Delete Row* popup.
|
|
|
|
Use the *Security Labels* panel to define security labels applied to the
|
|
function. Click the *Add* icon (+) to add each security label selection:
|
|
|
|
* Specify a security label provider in the *Provider* field. The named provider
|
|
must be loaded and must consent to the proposed labeling operation.
|
|
* Specify a a security label in the *Security Label* field. The meaning of a
|
|
given label is at the discretion of the label provider. PostgreSQL places no
|
|
restrictions on whether or how a label provider must interpret security
|
|
labels; it merely provides a mechanism for storing them.
|
|
|
|
Click the *Add* icon (+) to assign additional security labels; to discard a
|
|
security label, click the trash icon to the left of the row and confirm deletion
|
|
in the *Delete Row* popup.
|
|
|
|
Click the *SQL* tab to continue.
|
|
|
|
Your entries in the *Language* 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.
|
|
|
|
