clusterdb
CLUSTERDB(1) PostgreSQL Client Applications CLUSTERDB(1)
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
