I think it's probably the case that PLV8 is the most mature example of
wrapping a C++ library that is liable to throw C++ exceptions within
Postgres backend code, in a sane way (that is, avoiding unwinding the
stack via longjmp() over a part of the stack where a destructor needs
to be called, which is undefined in C++).
