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-option... ]  [  [ --verbose ]  [ -v ]  ]	[ --table | -t table  ]  [ dbname ]

       clusterdb [ connection-option... ]  [  [ --all ]  [ -a ]  ]  [  [ --verbose ]  [ -v ]  ]

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 affected.

       clusterdb is a wrapper around the SQL command CLUSTER [cluster(7)].  There is no effective difference between clustering databases via this
       utility and via other methods for accessing the server.

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 progress messages.

       -t table

       --table table
	      Cluster table only.

       -v

       --verbose
	      Print detailed information during processing.

       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 the value begins with a slash, it is used as the directory
	      for the Unix domain socket.

       -p port

       --port port
	      Specifies the TCP 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

       --no-password
	      Never issue a password prompt. If the server requires password authentication and a password is not available by other means such as
	      a .pgpass file, the connection attempt will fail. This option can be useful in batch jobs and scripts where no user  is  present	to
	      enter a password.

       -W

       --password
	      Force clusterdb to prompt for a password before connecting to a database.

	      This  option is never essential, since clusterdb will automatically prompt for a password if the server demands password authentica-
	      tion.  However, clusterdb will waste a connection attempt finding out that the server wants a password.  In some cases it  is  worth
	      typing -W to avoid the extra connection attempt.

ENVIRONMENT

       PGDATABASE

       PGHOST

       PGPORT

       PGUSER Default connection parameters

       This utility, like most other PostgreSQL utilities, also uses the environment variables supported by libpq (see in the documentation).

DIAGNOSTICS

       In  case of difficulty, see CLUSTER [cluster(7)] and psql(1) for discussions of potential problems and error messages.  The database server
       must be running at the targeted host. Also, any default connection settings and environment variables used by the libpq	front-end  library
       will apply.

EXAMPLES

       To cluster the database test:

       $ clusterdb test

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

       $ clusterdb --table foo xyzzy
