Tom Lane c82d931dd1 Fix the volatility marking of textanycat() and anytextcat(): they were marked 
immutable, but that is wrong in general because the cast from the polymorphic
argument to text could be stable or even volatile.  Mark them volatile for
safety.  In the typical case where the cast isn't volatile, the planner will
deduce the correct expression volatility after inlining the function, so
performance is not lost.  The just-committed fix in CREATE INDEX also ensures
this won't break any indexing cases that ought to be allowed.

Per discussion, I'm not bumping catversion for this change, as it doesn't
seem critical enough to force an initdb on beta testers.

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/.
