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.

       -q, --quiet
	   Do not display progress messages.

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

       -t table, --table=table
	   Reindex table only.

       -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
