Kevin Grittner 253de7e1eb Fix `make installcheck` for serializable transactions. 
Commit e5550d5fec added some new
tests for ALTER TABLE which involved table scans.  When
default_transaction_isolation = 'serializable' these acquire
relation-level SIReadLocks.  The test results didn't cope with
that.  Add SIReadLock as the minimum lock level for purposes of
these tests.

This could also be fixed by excluding this type of lock from the
my_locks view, but it would be a bug for SIReadLock to show up for
a relation which was not otherwise locked, so do it this way to
allow that sort of condition to cause a regression test failure.

There is some question whether we could avoid taking SIReadLocks
during these operations, but confirming the safety of that and
figuring out how to avoid the locks is not trivial, and would be
a separate patch.

Backpatch to 9.4 where the new tests were added.

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/.
