How about a proxy header (if such an animal exists). Maybe it is
possible to take pg_result, and all structs it references, and put it in
result-int.h. libpq-int.h would obviously include this. Also, any
external library, like libpqtypes, that need direct access to a result
can include result-int.h. This keeps pg_result and referenced structs
out of libpq-fe.h. From a libpq user's viewpoint, nothing has changed.
