 *

 * 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.

 *

 * src/include/postgres_ext.h
