REINDEXDB(1)            PostgreSQL 9.4.5 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. Multiple indexes can be recreated by writing
           multiple -i switches.

       -q
       --quiet
           Do not display progress messages.

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

       -t table
       --table=table
           Reindex table only. Multiple tables can be reindexed by writing
           multiple -t switches.

       -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
