* postgres_ext.h
*
* This file contains declarations of things that are visible
* external to Postgres. For example, the Oid type is part of a
* structure that is passed to the front end via libpq, and is
* accordingly referenced in libpq-fe.h.
*
* Declarations which are specific to a particular interface should
* go in the header file for that interface (such as libpq-fe.h). This
* file is only for fundamental Postgres declarations.
*
* User-written C functions don't count as "external to Postgres."
* Those function much as local modifications to the backend itself, and
* use header files that are otherwise internal to Postgres to interface
* with the backend.
