pg_upgrade needs to check whether certain non-upgradable data types appear anywhere on-disk in the source cluster. It knew that it has to check for these types being contained inside domains and composite types; but it somehow overlooked that they could be contained in arrays and ranges, too. Extend the existing recursive-containment query to handle those cases. We probably should have noticed this oversight while working on commit0ccfc2822and follow-ups, but we failed to :-(. The whole thing's possibly a bit overdesigned, since we don't really expect that any of these types will appear on disk; but if we're going to the effort of doing a recursive search then it's silly not to cover all the possibilities. While at it, refactor so that we have only one copy of the search logic, not three-and-counting. Also, to keep the branches looking more alike, back-patch the output wording change of commit1634d3615. Back-patch to all supported branches.

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.
