Amit Kapila 8e1fae1938 Move parallel vacuum code to vacuumparallel.c. 
This commit moves parallel vacuum related code to a new file
commands/vacuumparallel.c so that any table AM supporting indexes can
utilize parallel vacuum in order to call index AM callbacks (ambulkdelete
and amvacuumcleanup) with parallel workers.

Another reason for this refactoring is that the parallel vacuum isn't
specific to heap so it doesn't make sense to keep this code in
heap/vacuumlazy.c.

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/.
