reindexdb - reindex a PostgreSQL database




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

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

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


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

reindexdb is a wrapper around the SQL command REINDEX [reindex(7)]. There is no effective difference between reindexing databases via this utility and via other methods for accessing the server.


reindexdb accepts the following command-line arguments:
Reindex all databases.
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.
Echo the commands that reindexdb generates and sends to the server.
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.
Force password prompt.


  Default connection parameters


In case of difficulty, see REINDEX [reindex(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.


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 the documentation for more information.


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
