|

|
* 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.
