Andres Freund 0cbc72ca72 Add isolation tests for the combination of EPQ and triggers.
As evidenced by bug #16036 this area is woefully under-tested. Add
fairly extensive tests for the combination.

Backpatch back to 9.6 - before that isolationtester was not capable
enough. While we don't backpatch tests all the time, future fixes to
trigger.c would potentially look different enough in 12+ from the
earlier branches that introducing bugs during backpatching is more
likely than normal. Also, it's just a crucial and undertested area of
the code.

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:

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
