[GENERAL] test datatype for ANY

[NosyMan]

Hi there,

How can I test the type of a parameter passed to a function via ANY data type? 
I want something like this:

CREATE OR REPLACE FUNCTION myfunction(_param ANY) RETURNS INTEGER AS $$
        BEGIN
                IF "_param IS OF INTEGER TYPE" THEN
                        -- do something with INTEGER
                END IF;
                IF "param is of BOOLEAN TYPE" THEN
                        -- do something with BOOLEAN
                END IF;
                RETURN;
        END;
$$ LANGUAGE plpgsql;


Thanks,
Nosy
