REINDEXDB(1) PostgreSQL Client Applications REINDEXDB(1)NAMEreindexdb - reindex a PostgreSQL database
SYNOPSISreindexdb [ connection-option... ] [ --table | -t table ] [ --index
| -i index ] [ dbname ]
reindexdb [ connection-option... ] [ --all | -a ]
reindexdb [ connection-option... ] [ --system | -s ] [ dbname ]
DESCRIPTIONreindexdb 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.
OPTIONSreindexdb 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 connec‐
tion 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 exten‐
sion 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 automati‐
cally 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 envi‐
ronment variables supported by libpq (see in the documentation).
DIAGNOSTICS
In case of difficulty, see REINDEX [reindex(7)] and psql(1) for discus‐
sions of potential problems and error messages. The database server
must be running at the targeted host. Also, any default connection set‐
tings and environment variables used by the libpq front-end library
will apply.
NOTESreindexdb 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
