REINDEXDB(1)			  PostgreSQL 9.2.7 Documentation		     REINDEXDB(1)

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(7). 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.

       [-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.

       -i index, --index=index
	   Recreate index only.

       -q, --quiet
	   Do not display progress messages.

       -s, --system
	   Reindex database's system catalogs.

       -t table, --table=table
	   Reindex table only.

       -V, --version
	   Print the reindexdb version and exit.

       -?, --help
	   Show help about reindexdb command line arguments, and exit.

       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, --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 reindexdb to prompt for a password before connecting to a database.

	   This option is never essential, since reindexdb will automatically prompt for a
	   password if the server demands password authentication. However, reindexdb 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.

       --maintenance-db=dbname
	   Specifies the name of the database to connect to discover what other databases should
	   be reindexed. If not specified, the postgres database will be used, and if that does
	   not exist, template1 will be used.

ENVIRONMENT
       PGDATABASE, PGHOST, PGPORT, PGUSER
	   Default connection parameters

       This utility, like most other PostgreSQL utilities, also uses the environment variables
       supported by libpq (see Section 31.14, "Environment Variables", in the documentation).

DIAGNOSTICS
       In case of difficulty, see 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.

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 Section
       31.15, "The Password File", in the documentation 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
