Commit 7358abcc60 taught the planner to
store information about Append node consolidation in the final plan,
but it forgot that child_append_relid_sets needs to be adjusted
at setrefs.c time just like every other place where we store RTIs
in a plan tree. Fix that.
Although this can cause incorrect plan advice to be emitted in cases
involving multi-level partitioning, it seems more appropriate to put
the test case for it in pg_overexplain, so this commit does that.

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.
