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
