       reindexdb - reindex a PostgreSQL database


       reindexdb [connection-option...] [option...] [ --schema | -S schema ]...
                 [ --table | -t table ]...  [ --index | -i index ]...  [dbname]

       reindexdb [connection-option...] [option...] --all | -a

       reindexdb [connection-option...] [option...] --system | -s  [dbname]


       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


       reindexdb accepts the following command-line arguments:

           Reindex all databases.

       [-d] 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.

           Echo the commands that reindexdb generates and sends to the server.

       -i index
           Recreate index only. Multiple indexes can be recreated by writing multiple -i

           Do not display progress messages.

           Reindex database's system catalogs.

       -S schema
           Reindex schema only. Multiple schemas can be reindexed by writing multiple -S

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

           Print detailed information during processing.

           Print the reindexdb version and exit.

           Show help about reindexdb command line arguments, and exit.

       reindexdb also accepts the following command-line arguments for connection parameters:

       -h 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
           Specifies the TCP port or local Unix domain socket file extension on which the server
           is listening for connections.

       -U username
           User name to connect as.

           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.

           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.

           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.


           Default connection parameters

       This utility, like most other PostgreSQL utilities, also uses the environment variables
       supported by libpq (see Section 34.14).


       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.


       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 34.15 for more information.


       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
