IMHO using the C pre-processor to make C look like some other language:
- makes the code harder to read as readers have to learn the dialect first
- makes the code harder to debug, since debugging tools don't know the dialect but only the C it is translated into
This exception implementation has the obvious(?) problem of using
setjump()/longjmp() where sigsetjmp()/siglongjmp() would probably be
necessary for postgresql.
There are places too where this implementation would just plain not
work and so couldn't be used: setjmp(), longjmp(), sigsetjump(), and
siglongjmp() are not async safe signal functions and so can't be
called in signal handlers, for a start.
