There were many PG_GETARG_* calls, mostly around gin, gist, spgist
code, that were commented out, presumably to indicate that the
argument was unused and to indicate that it wasn't forgotten or
miscounted. But keeping commented-out code updated with refactorings
and style changes is annoying. So this commit changes them to
#ifdef NOT_USED
blocks, which is a style already in use. That way, at least the
indentation and syntax highlighting works correctly, making some of
these blocks much easier to read.
An alternative would be to just delete that code, but there is some
value in making unused arguments explicit, and some of this arguably
serves as example code for index AM APIs.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
