Commit 33bd250f6c could have done with
some more review:
Adjust coding so that compilers unfamiliar with elog/ereport don't complain
about uninitialized values.
Fix misuse of PG_GETARG_INT16 to retrieve arguments declared as "integer"
at the SQL level. (This was evidently copied from cube_ll_coord and
cube_ur_coord, but those were wrong too.)
Fix non-style-guide-conforming error messages.
Fix underparenthesized if statements, which pgindent would have made a
hash of, and remove some unnecessary parens elsewhere.
Run pgindent over new code.
Revise documentation: repeated accretion of more operators without any
rethinking of the text already there had left things in a bit of a mess.
Merge all the cube operators into one table and adjust surrounding text
appropriately.

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.
