NAME

       user_clusters - File linking users to PostgreSQL clusters

DESCRIPTION

       This  file  maps users against the database clusters to which they will connect by default. However, every user can override these settings
       in ~/.postgresqlrc.

       When scanning this file, the first matching line will be used.  It is a good idea to provide a default explicitly, with a final line  where
       both user and group are set to *.

       If  there  is  no default, the implicit default is to connect to the cluster whose postmaster is listening on port 5432 and to the database
       matching the user's login name.

FORMAT

       Comments are introduced by the character #.  Comments may follow data on a line; the first comment character terminates the  data.  Leading
       whitespace and blank lines are ignored.

       Each uncommented, non-blank line must describe a user, group or the default (where both user and group are set to *).

       Fields must be given in the following order, separated by white space:

       USER   The login id of the Unix user to whom this line applies. The wildcard character * means any user.

       GROUP  The group name of the Unix group to which this line applies. The wildcard character * means any group.

       VERSION
	      The major PostgreSQL version of the cluster to connect to.

       CLUSTER
	      The name of a cluster to connect to. A remote cluster is specified with host:port. If port is empty, it defaults to 5432.

       DATABASE
	      Within  the  cluster,  the database to which the user will connect by default if he does not specify a database on the command line.
	      If this is *, the default database will be the one named by the user's login id.

NOTES

       Since the first matching line is used, the default line must come last.

NAME

       clusterdb - cluster a PostgreSQL database

SYNOPSIS

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

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

DESCRIPTION

       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 environment 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 password each time. It is convenient to have a
       $HOME/.pgpass file in such cases.

OPTIONS

       clusterdb accepts the following command-line arguments:

       -a

       --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.

       -e

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

       -q

       --quiet
	      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

       -W

       --password
	      Force password prompt.

DIAGNOSTICS

       CLUSTER
	      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.

ENVIRONMENT

       PGDATABASE

       PGHOST

       PGPORT

       PGUSER Default connection parameters.

EXAMPLES

       To cluster the database test:

       $ clusterdb test

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

       $ clusterdb --table foo xyzzy
