Tom Lane 5b68d81697 Fix contrib/postgres_fdw's remote-estimate representation of array Params. 
We were emitting "(SELECT null::typename)", which is usually interpreted
as a scalar subselect, but not so much in the context "x = ANY(...)".
This led to remote-side parsing failures when remote_estimate is enabled.
A quick and ugly fix is to stick in an extra cast step,
"((SELECT null::typename)::typename)".  The cast will be thrown away as
redundant by parse analysis, but not before it's done its job of making
sure the grammar sees the ANY argument as an a_expr rather than a
select_with_parens.  Per an example from Hannu Krosing.

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/.
