I'm not either, but given that he can get as far as building a library
that will load into the backend, it's surprising that it would fall down
on the small matter of passing function arguments. It seems worth
trying to understand exactly what's happening there.
Greg, how sure are you about the diagnosis of "PG_ARGISNULL always
returns true" --- have you stepped through your code with a debugger?
