A PostgreSQL user can register a new procedural language with a PostgreSQL database. Subsequently, functions and trigger procedures can be defined in this new language. The user must have the PostgreSQL superuser privilege to register a new language.

New languages are created within Create Language Wizard. In order to run the wizard you should either

•	select the Object \| Create Database Object... main menu item;

•	select the Language icon in the Create Database Object dialog

•	select the Languages list or any object from that list in the explorer tree;

•	select the Create New Language... item from the popup menu

•	open the database in Database Editor and the Languages tab there;

•	press the Insert key or select the Create New Language... item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar).

To create a new language with the same properties as one of the existing languages has:

•	select the Object \| Duplicate Database Object... main menu item;

•	follow the instructions of Duplicate Object Wizard.

Languages can be edited within Language Editor. In order to run the editor you should either

•	select the language for editing in the explorer tree (type the first letters of the language name for quick search);

•	select the Edit Language ... item from the popup menu

•	open the database in Database Editor and the Languages tab there;

•	select the language to edit;

•	press the Enter key or select the Edit Language item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar).

You can change the name of the language using the Rename Language dialog. To open the dialog you should either

•	select the language to rename in the explorer tree;

•	select the Rename Language item from the popup menu

•	open the database in Database Editor and the Languages tab there;

•	select the language to rename;

•	select the Rename Language item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar).

To drop a language:

•	select the language to drop in the explorer tree;

•	select the Drop Language item from the popup menu

•	open the database in Database Editor and the Languages tab there;

•	select the language to drop;

•	press the Delete key or select the Drop Language item from the popup menu (alternatively, you may use the corresponding link of the Navigation Bar)

and confirm dropping in the dialog window.
