One slight problem with this is the common port/*.c idiom would require
an extra include:
#ifndef FRONTEND
#include "postgres.h"
#else
#include "postgres_fe.h"
#include "pgassert.h" /* <--- new line required here */
#endif /* FRONTEND */
If this is seen as a serious issue (I don't think so) then we would have
to include pgassert.h into postgres_fe.h which would make the whole
thing pointless (i.e. the same as just having the definitions in c.h).
