     *
     * 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.
     *
