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 commit 0ccfc2822 and 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 commit 1634d3615. Back-patch to all supported branches.

This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions.
