overexplain_range_table() emitted the "Unprunable RTIs" and "Result RTIs" properties before closing the "Range Table" group. In the JSON and YAML formats the Range Table group is rendered as an array of RTE objects, so emitting key/value pairs inside it produced structurally invalid output. The XML format had a related oddity, with these elements nested inside <Range-Table> rather than appearing as its siblings. These fields are properties of the PlannedStmt as a whole, not of any individual RTE, so close the Range Table group before emitting them. They now appear as siblings of "Range Table" in the parent Query object, which is what was intended. Also add a test exercising FORMAT JSON with RANGE_TABLE so that any future regression in the output structure is caught.

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.
