Get rid of the fundamentally indefensible assumption that "long long int" exists and is exactly 64 bits wide on every platform Postgres runs on. Instead let the configure script select the type to use for "pg_int64". This is a bit of a pain in the rear since we do not want to pollute client namespace with all the random symbols that pg_config.h defines; instead we have to create a separate generated header file, "pg_config_ext.h". But now that the infrastructure is there, we might have the ability to add some other stuff that's long been wanting in this area.

|
|
* For example, the Oid type is part of the API of libpq and other libraries.
|
|

|

* Declarations which are specific to a particular interface should
|

* 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.
