Basic foreign table support. 

Foreign tables are a core component of SQL/MED.  This commit does
not provide a working SQL/MED infrastructure, because foreign tables
cannot yet be queried.  Support for foreign table scans will need to
be added in a future patch.  However, this patch creates the necessary
system catalog structure, syntax support, and support for ancillary
operations such as COMMENT and SECURITY LABEL.

Shigeru Hanada, heavily revised by Robert Haas

<command>ALTER FOREIGN TABLE</command> changes the definition of an
existing foreign table. There are several subforms:

<varlistentry>
<term><literal>ADD COLUMN</literal></term>
<listitem>
<para>
This form adds a new column to the foreign table, using the same syntax as
<xref linkend="SQL-CREATEFOREIGNTABLE">.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><literal>DROP COLUMN [ IF EXISTS ]</literal></term>
<listitem>
<para>
This form drops a column from a foreign table.
You will need to say <literal>CASCADE</> if
anything outside the table depends on the column; for example,
views.
If <literal>IF EXISTS</literal> is specified and the column
does not exist, no error is thrown. In this case a notice
is issued instead.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><literal>SET DATA TYPE</literal></term>
<listitem>
<para>

<para>

<literal>ADD</>, <literal>SET</>, and <literal>DROP</>
specify the action to be performed. <literal>ADD</> is assumed
if no operation is explicitly specified. Option names must be
unique; names and values are also validated using the foreign
data wrapper library.
</para>
</listitem>
</varlistentry>
</variablelist>
</para>
<para>
All the actions except <literal>RENAME</literal> and <literal>SET SCHEMA</>
can be combined into
a list of multiple alterations to apply in parallel. For example, it
is possible to add several columns and/or alter the type of several
columns in a single command.
</para>
<para>
You must own the table to use <command>ALTER FOREIGN TABLE</>.
To change the schema of a foreign table, you must also have
<literal>CREATE</literal> privilege on the new schema.
To add the table as a new child of a parent table, you must own the
parent table as well.
To alter the owner, you must also be a direct or indirect member of the new
owning role, and that role must have <literal>CREATE</literal> privilege on
the table's schema. (These restrictions enforce that altering the owner
doesn't do anything you couldn't do by dropping and recreating the table.
However, a superuser can alter ownership of any table anyway.)
