Tom Lane 404946d401 Fix some more omissions in pg_upgrade's tests for non-upgradable types. 
Commits 29aeda6e4 et al closed up some oversights involving not checking
for non-upgradable types within container types, such as arrays and
ranges.  However, I only looked at version.c, failing to notice that
there were substantially-equivalent tests in check.c.  (The division
of responsibility between those files is less than clear...)

In addition, because genbki.pl does not guarantee that auto-generated
rowtype OIDs will hold still across versions, we need to consider that
the composite type associated with a system catalog or view is
non-upgradable.  It seems unlikely that someone would have a user
column declared that way, but if they did, trying to read it in another
PG version would likely draw "no such pg_type OID" failures, thanks
to the type OID embedded in composite Datums.

To support the composite and reg*-type cases, extend the recursive
query that does the search to allow any base query that returns
a column of pg_type OIDs, rather than limiting it to exactly one
starting type.

As before, back-patch to all supported branches.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  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.

The latest version of this software may be obtained at
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
