Well you could imagine doing this for all our types by doing:
search and replace int4 -> pgint4 etc.
add #ifndef int4 #define int4 pgint4 at the end of postgres.h
That way third-party apps which define their own int4 would be
required to use pgint4. But third-party apps which don't could
continue to use int4. All struct interfaces etc would be defined using
pgint4 directly so wouldn't be affected by any unusual definition of
int4.
The trick would be to ensure that nothing in the postgres interfaces
depend on the bool or int4 definitions. That would be easy to ensure
after the search/replace but hard to guarantee long-term.
