Well one thing that might be useful for a c++ procedural language would be
catching C++ exceptions and translating them into ereports which could then be
caught in Postgres.

That's actually what I thought you had done but I just reread your mail and
realized you only handled unhandled exceptions which cause the backend to die.

The other way around could be useful too -- catching ereports/elogs within a
backend API call from C++ code and throwing a C++ exception. I'm not sure if
that's doable though.
