Tom Lane 96a7e3a261 Improve regression test case to avoid depending on system catalog stats. In commit `95f4e59c32` I added a regression test case that examined the plan of a query on system catalogs. That isn't a terribly great idea because the catalogs tend to change from version to version, or even within a version if someone makes an unrelated regression-test change that populates the catalogs a bit differently. Usually I try to make planner test cases rely on test tables that have not changed since Berkeley days, but I got sloppy in this case because the submitted crasher example queried the catalogs and I didn't spend enough time on rewriting it. But it was a problem waiting to happen, as I was rudely reminded when I tried to port that patch into Salesforce's Postgres variant :-(. So spend a little more effort and rewrite the query to not use any system catalogs. I verified that this version still provokes the Assert if 95f4e59c32866716's code fix is reverted. I also removed the EXPLAIN output from the test, as it turns out that the assertion occurs while considering a plan that isn't the one ultimately selected anyway; so there's no value in risking any cross-platform variation in that printout. Back-patch to 9.2, like the previous patch.		2015-08-13 13:25:02 -04:00

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/.
