David Rowley 8d29d45d9b Fix assert failure in expand_grouping_sets
linitial_node() fails in assert enabled builds if the given pointer is
not of the specified type.  Here the type is IntList.  The code thought
it should be expecting List, but it was wrong.

In the existing tests which run this code the initial list element is
always NIL.  Since linitial_node() allows NULL, we didn't trigger any
assert failures in the existing regression tests.

There is still some discussion as to whether we need a few more tests in
this area, but for now, since beta2 is looming, fix the bug first.

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:

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.
