Tom Lane 30168be8f7 Remove plpgsql's special-case code paths for SET/RESET. 
In the wake of 84f5c2908, it's no longer necessary for plpgsql to
handle SET/RESET specially.  The point of that was just to avoid
taking a new transaction snapshot prematurely, which the regular code
path through _SPI_execute_plan() now does just fine (in fact better,
since it now does the right thing for LOCK too).  Hence, rip out a
few lines of code, going back to the old way of treating SET/RESET
as a generic SQL command.  This essentially reverts all but the
test cases from b981275b6.

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/.
