We've been creating duplicate RTEs for partitioned tables just because we do so for regular inheritance parent tables. But unlike regular-inheritance parents which are themselves regular tables and thus need to be scanned, partitioned tables don't need the extra RTE. This makes the conditions for building a child RTE the same as those for building an AppendRelInfo, allowing minor simplification in expand_single_inheritance_child. Since the planner's actual processing is driven off the AppendRelInfo list, nothing much changes beyond that, we just have one fewer useless RTE entry.

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.
