* postgres_ext.h
*
* This file contains declarations of things that are visible everywhere
* in PostgreSQL *and* are visible to clients of frontend interface libraries.
* For example, the Oid type is part of the API of libpq and other libraries.
*
* 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.
