Defining PostgreSQL Languages

The following properties are applicable to a PostgreSQL Language object.

Tab	Section	Property	Description	Additional Information
		Name	Specifies the name of the language
		Use Replace Syntax	Specifies whether the REPLACE syntax is used	Selecting this option replaces the syntax with the new DDL that is generated during Forward Engineering
		Generate	Specifies whether a SQL statement for the table is generated during forward engineering
General	General Options	Is Trusted	Specifies that the language does not grant access to data that the user would not otherwise have	If you omit this keyword, only users with the PostgreSQL superuser privilege can use this language to create new functions.
		Procedural	Specifies the procedural language
		Call Handler	Specifies a previously registered function that executes procedural language functions. It must be written in a compiled language like C with version 1 call convention and registered with PostgreSQL as a function that takes no arguments and returns the language_handler type.
		Inline Handler	Specifies a previously registered function that executes anonymous code blocks (DO commands) in this language. If no inline_handler function is specified, the language does not support anonymous code blocks.	The handler function takes one argument of type internal, representing the DO command’s internal representation, and typically returns void. The return value of the handler is ignored.
		Validator	Specifies the name of previously registered function that validates new functions created in the language. New functions are not checked upon creation if no validator function is specified.	The validator function takes one argument of type oid, representing the OID of the to-be-created function, and typically returns void.
