No, we don't have any concept of member functions. Just create the
composite type (I'm assuming it needs to be composite) and then create
functions that take it as parameter.
Note that because PG allows function overloading, there's no conflict
between, say, to_string(D_Temp_Element) and to_string(Some_Other_Type).
If you were only using member functions to prevent that kind of
conflict, I don't think you need to worry too much.
