    Fix multiple bugs in extension dropping.
    Tom Lane authored 
    When we implemented extensions, we made findDependentObjects() treat
EXTENSION dependency links similarly to INTERNAL links.  However, that
logic contained an implicit assumption that an object could have at most
one INTERNAL dependency, so it did not work correctly for objects having
both INTERNAL and DEPENDENCY links.  This led to failure to drop some
extension member objects when dropping the extension.  Furthermore, we'd
never actually exercised the case of recursing to an internally-referenced
(owning) object from anything other than a NORMAL dependency, and it turns
out that passing the incoming dependency's flags to the owning object is
the Wrong Thing.  This led to sometimes dropping a whole extension silently
when we should have rejected the drop command for lack of CASCADE.

Since we obviously were under-testing extension drop scenarios, add some
regression test cases.  Unfortunately, such test cases require some
extensions (duh), so we can't test for problems in the core regression
tests.  I chose to add them to the earthdistance contrib module, which is
a good test case because it has a dependency on the cube contrib module.

Back-patch to 9.1.  Arguably these are pre-existing bugs in INTERNAL
dependency handling, but since it appears that the cases can never arise
pre-9.1, I'll refrain from back-patching the logic changes further than
that.

    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.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  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/.
