I attach a little patch to make CLUSTER set and reset the indisclustered

bit on the indexes.

I also attach clusterdb and clusterdb.sgml; both of them are blatant
rips of vacuumdb and vacuumdb.sgml, but get the job done.  Please review
them, as I'm probably making a lot of mistakes with SGML and I can't
compile it here.

vacuumdb itself is not very comfortable to use when the databases have
passwords, because it has to connect once for each table (I can probably
make it connect only once for each database; should I?).  Because of
this I added a mention of PGPASSWORDFILE in the documentation, but I
don't know if that is the correct place for that.

<title>Description</title>
<para>
<application>clusterdb</application> is a utility for clustering tables inside a
<productname>PostgreSQL</productname> database.
</para>
<para>
<application>clusterdb</application> is a shell script wrapper around the
backend command
<xref linkend="SQL-CLUSTER" endterm="SQL-CLUSTER-title"> via
the <productname>PostgreSQL</productname> interactive terminal
<xref linkend="APP-PSQL">. There is no effective
difference between clustering databases via this or other methods.
<application>psql</application> must be found by the script and
a database server must be running at the targeted host. Also, any default
settings and environment variables available to <application>psql</application>
and the <application>libpq</application> front-end library do apply.
</para>
<para>
<application>clusterdb</application> will need to connect several times to the
<productname>PostgreSQL</productname> server, asking for the password each
time. It will probably be very convenient to have a PGPASSWORDFILE in that case.
</para>

<listitem>
<para>
Specifies the name of the database to be clustered.
If this is not specified and <option>-a</option> (or

from the environment variable <envar>PGDATABASE</envar>. If
that is not set, the user name specified for the connection is
used.
