I think the issue is portability. Remember that this type needs to work on
Windows as well as all POSIX platforms and AIX.

Readline is for PSQL command completion and history. As for the rest, they
are *optional* modules that apparently your RPM builder chose to include; I
build from source and my only dependencies are bison, flex, gcc and perl.

Is it portable to all platforms we support? How does it generate its machine
identifier?

One of the differences between an add-in and core code is support for all
PostgreSQL platforms.
