5 | * This file contains declarations of things that are visible everywhere |
6 | * in PostgreSQL *and* are visible to clients of frontend interface libraries. |
7 | * For example, the Oid type is part of the API of libpq and other libraries. |
8 | * |
9 | * Declarations which are specific to a particular interface should |
10 | * go in the header file for that interface (such as libpq-fe.h). This |
11 | * file is only for fundamental Postgres declarations. |
12 | * |
13 | * User-written C functions don't count as "external to Postgres." |
14 | * Those function much as local modifications to the backend itself, and |
15 | * use header files that are otherwise internal to Postgres to interface |
16 | * with the backend. |
