Tom Lane b53c841e5e Fix incorrect trigger-property updating in ALTER CONSTRAINT. 
The code to change the deferrability properties of a foreign-key constraint
updated all the associated triggers to match; but a moment's examination of
the code that creates those triggers in the first place shows that only
some of them should track the constraint's deferrability properties.  This
leads to odd failures in subsequent exercise of the foreign key, as the
triggers are fired at the wrong times.  Fix that, and add a regression test
comparing the trigger properties produced by ALTER CONSTRAINT with those
you get by creating the constraint as-intended to begin with.

Per report from James Parks.  Back-patch to 9.4 where this ALTER
functionality was introduced.

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:

	http://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
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
