Hmm, that does sound problematic. You can always build with
-fno-exceptions (gcc; I think other compilers offer related options) and
adopt Pg's error handling scheme instead, though.

In general it's possible to use exceptions in C++ code that's being
called from C so long as you make sure you catch all possible exceptions
at the C/C++ interface point.

Yep... unless you have to call C++ libraries or the like I'd be
reluctant to take all the possible bother on board. That's despite
personally having a strong preference for C++.
