- * 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.
