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 [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.

       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  authentica-
	      tion.   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.

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 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.

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 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
