    by loadable modules. Please refer to the documentation of the
    procedural language in question for details about the syntax and how the
    function body is interpreted for each language.

    <SPAN

    Refer to <A

    Other languages can be defined by users.
    The basics of developing a new procedural language are covered in <A
