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 connec-
              tions.

       -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
