REINDEXDB(1)            PostgreSQL Client Applications            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 [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  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.


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
