Right, and even pqcomm.h (to which the comment refers) is material that
is known to libpq (and other implementors of the FE/BE protocol), but is
not exposed to client applications.
This comment in pqcomm.c might be helpful:
* At one time, libpq was shared between frontend and backend, but now* the backend's "backend/libpq" is quite separate
from"interfaces/libpq".* All that remains is similarities of names to trap the unwary...
The only material that is officially part of the libpq client API is
libpq-fe.h (and postgres_ext.h which it includes). Anyone including
other headers does so at their own risk.
