Tom Lane d002f16c6e Add a regression test script dedicated to exercising system views.
Quite a few of our built-in system views were not exercised anywhere
in the regression tests.  This is perhaps not so exciting for the ones
that are simple projections/joins of system catalogs, but for the ones
that are wrappers for set-returning C functions, the omission translates
directly to lack of test coverage for those functions.

In many cases, the reason for the omission is that the view doesn't have
much to do with any specific SQL feature, so there's no natural place to
test it.  To remedy that, invent a new script sysviews.sql that's dedicated
to testing SRF-based views.  Move a couple of tests that did fit this
charter into the new script, and add simple "count(*)" based tests of
other views within the charter.  That's enough to ensure we at least
exercise the main code path through the SRF, although it does little to
prove that the output is sane.

More could be done here, no doubt, and I hope someone will think about
how we can test these views more thoroughly.  But this is a starting
point.

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/.
