       clusterdb - cluster a PostgreSQL database

       clusterdb [ connection-options... ] [ --table | -t table  ] [ dbname ]

       clusterdb [ connection-options... ] [ --all | -a ]

       clusterdb  is  a utility for reclustering tables in a PostgreSQL database. It finds tables
       that have previously been clustered, and clusters them again on the same  index	that  was
       last used. Tables that have never been clustered are not touched.

       clusterdb  is  a  shell script wrapper around the backend command CLUSTER [cluster(7)] via
       the PostgreSQL interactive terminal psql(1). There  is  no  effective  difference  between
       clustering  databases  via  this or other methods.  psql must be found by the script and a
       database server must be running at the targeted host. Also, any default settings and envi-
       ronment variables available to psql and the libpq front-end library do apply.

       clusterdb might need to connect several times to the PostgreSQL server, asking for a pass-
       word each time. It is convenient to have a $HOME/.pgpass file in such cases.

       clusterdb accepts the following command-line arguments:


       --all  Cluster all databases.

       [-d] dbname

       [--dbname] dbname
	      Specifies the name of the database to be clustered.  If this is not  specified  and
	      -a  (or --all) is not used, the database name is read from the environment variable
	      PGDATABASE. If that is not set, the user name specified for the connection is used.


       --echo Echo the commands that clusterdb generates and sends to the server.


	      Do not display a response.

       -t table

       --table table
	      Clusters table only.

       clusterdb also accepts the following command-line arguments for connection parameters:

       -h host

       --host host
	      Specifies the host name of the machine on which the  server  is  running.  If  host
	      begins with a slash, it is used as the directory for the Unix domain socket.

       -p port

       --port port
	      Specifies  the  Internet	TCP/IP port or local Unix domain socket file extension on
	      which the server is listening for connections.

       -U username

       --username username
	      User name to connect as


	      Force password prompt.

	      Everything went well.

       clusterdb: Cluster failed.
	      Something went wrong. clusterdb is only a wrapper script. See CLUSTER  [cluster(7)]
	      and  psql(1)  for  a  detailed discussion of error messages and potential problems.
	      Note that this message may appear once per table to be clustered.




       PGUSER Default connection parameters.

       To cluster the database test:

       $ clusterdb test

       To cluster a single table foo in a database named xyzzy:

       $ clusterdb --table foo xyzzy

       CLUSTER [cluster(7)]
