Description

reindexdb is a utility for rebuilding indexes in Greenplum Database, and is a wrapper around the SQL command REINDEX.

Options

-a | --all
Reindex all databases.
[-d] dbname | [--dbname] dbname
Specifies the name of the database to be reindexed. If this is not specified and -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.
-i index | --index index
Recreate index only.
-q | --quiet
Do not display a response.
-s | --system
Reindex system catalogs.
-t table | --table table
Reindex table only.
Connection Options
-h host | --host host
Specifies the host name of the machine on which the Greenplum master database server is running. If not specified, reads from the environment variable PGHOST or defaults to localhost.
-p port | --port port
Specifies the TCP port on which the Greenplum master database server is listening for connections. If not specified, reads from the environment variable PGPORT or defaults to 5432.
-U username | --username username
The database role name to connect as. If not specified, reads from the environment variable PGUSER or defaults to the current system user name.
-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 a password prompt.

Notes

reindexdb might need to connect several times to the master server, asking for a password each time. It is convenient to have a ~/.pgpass file in such cases.

Examples

To reindex the database mydb:

reindexdb mydb

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

reindexdb --table foo --index bar abcd
