Fujii Masao 4faea7fdf1 Revert recent change of ScanOption values and renumber SO_TYPE_TIDSCAN.
Commit 598b466e80 in v12 renumbered ScanOption enum values to add
the option for Tid scan. But the change of the codes assigned to
the existing values caused an ABI break and may break some extensions
depending on them. This should be avoided in minor version.

This commit reverts the renumbering of ScanOption enum values made by
commit 598b466e80 in v12 and put the ScanOption for Tid scan with new value.
This is applied only to v12.

Per complaint from Tom Lane.

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/.
