Yeah, the general policy is that .h files should not explicitly include
c.h (nor postgres.h nor postgres_fe.h). Instead, .c files should include
the appropriate one of those three files first. This allows sharing of
.h files more easily across frontend/backend/common environments.
I'm not sure where this is documented either.
