The immediate problem is that you didn't declare the function as extern
"C" so it doesn't follow C naming conventions. In general, though, it's
fairly difficult to use any interesting C++ capabilities in a Postgres
backend module, because the main backend does not contain the C++
library. So, for instance, I'd not expect C++ exceptions or RTTI to
work at all well.
