Michael Paquier 4c9c359d38 Refactor code in tablecmds.c to check and process tablespace moves Two code paths of tablecmds.c (for relations with storage and without storage) use the same logic to check if the move of a relation to a new tablespace is allowed or not and to update pg_class.reltablespace and pg_class.relfilenode. A potential TABLESPACE clause for REINDEX, CLUSTER and VACUUM FULL needs similar checks to make sure that nothing is moved around in illegal ways (no mapped relations, shared relations only in pg_global, no move of temp tables owned by other backends). This reorganizes the existing code of ALTER TABLE so as all this logic is controlled by two new routines that can be reused for the other commands able to move relations across tablespaces, limiting the number of code paths in need of the same protections. This also removes some code that was duplicated for tables with and without storage for ALTER TABLE.

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/.
