Like INT64_FORMAT and UINT64_FORMAT, these macros produce format strings for 64-bit integers. However, INT64_HEX_FORMAT and UINT64_HEX_FORMAT generate the output in hexadecimal instead of decimal. Besides introducing these macros, this commit makes use of them in several places. This was originally intended to be part of commit5d6187d2a2, but I left it out because I felt there was a nonzero chance that back-patching these new macros into c.h could cause problems with third-party code. We tend to be less cautious with such changes in new major versions. Note that UINT64_HEX_FORMAT was originally added in commitee1b30f128, but it was placed in test_radixtree.c, so it wasn't widely available. This commit moves UINT64_HEX_FORMAT to c.h.

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.
