Tom Lane f3faf35f37 Don't create pg_type entries for sequences or toast tables. Commit `f7f70d5e2` left one inconsistency behind: we're still creating pg_type entries for the composite types of sequences and toast tables, but not arrays over those composites. But there seems precious little reason to have named composite types for toast tables, and not much more to have them for sequences (especially given the thought that sequences may someday not be standalone relations at all). So, let's close that inconsistency by removing these composite types, rather than adding arrays for them. This buys back a little bit of the initial pg_type bloat added by the previous patch, and could be a significant savings in a large database with many toast tables. Aside from a small logic rearrangement in heap_create_with_catalog, this patch mostly needs to clean up some places that were assuming that pg_class.reltype always has a valid value. Those are really pre-existing bugs, given that it's documented otherwise; notably, the plpgsql changes fix code that gives "cache lookup failed for type 0" on indexes today. But none of these seem interesting enough to back-patch. Also, remove the pg_dump/pg_upgrade infrastructure for propagating a toast table's pg_type OID into the new database, since we no longer need that.

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/.
