13.14 reindexdb

Name

reindexdb -- reindex a PostgreSQL database

Synopsis

reindexdb [connection-option...] [--table | -t table]
 [--index | -i index] [dbname]

reindexdb [connection-option...] [--all | -a]

reindexdb [connection-option...] [--system | -s] [dbname]

Description

reindexdb is a utility for rebuilding indexes in a PostgreSQL database.

reindexdb is a wrapper around the SQL command REINDEX. There is no effective difference between reindexing databases via this utility and via other methods for accessing the server.

Options

reindexdb accepts the following command-line arguments:

-a

--all

Reindex all databases.

-s

--system

Reindex database's system catalogs.

-t table

--table table

Reindex table only.

-i index

--index index

Recreate index only.

[-d] dbname

[--dbname] dbname

Specifies the name of the database to be reindexed. 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 reindexdb generates and sends to the server.

-q

--quiet

Do not display a response.

reindexdb 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

--password

Force password prompt.

Environment

PGDATABASE

PGHOST

PGPORT

PGUSER

Default connection parameters

Diagnostics

In case of difficulty, see REINDEX and psql 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.

Notes

reindexdb might need to connect several times to the PostgreSQL server, asking for a password each time. It is convenient to have a ‘~/.pgpass’ file in such cases. See Volume 2: The Password File for more information.

Examples

To reindex the database test:

$ reindexdb test

To reindex the table foo and the index bar in a database named abcd:

$ reindexdb --table foo --index bar abcd
