reindexdb -- reindex a PostgreSQL database
reindexdb [connection-option...] [--table | -t table] [--index | -i index] [dbname]
reindexdb [connection-option...] [--all | -a]
reindexdb [connection-option...] [--system | -s] [dbname]
reindexdb is a utility for rebuilding indexes in a PostgreSQL database.
reindexdb is a wrapper around the SQL
There is no effective difference between reindexing databases via
this utility and via other methods for accessing the server.
reindexdb accepts the following command-line arguments:
- Reindex all databases.
Specifies the name of the database to be reindexed.
If this is not specified and
--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.
- Recreate index only.
- Do not display progress messages.
- Reindex database's system catalogs.
- Reindex table only.
- 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:
- 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.
- Specifies the TCP port or local Unix domain socket file extension on which the server is listening for connections.
- 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
-Wto avoid the extra connection attempt.
- Default connection parameters
This utility, like most other PostgreSQL utilities, also uses the environment variables supported by libpq (see Volume 2: Environment Variables).
In case of difficulty, see
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 Volume 2: The Password File for more information.
To reindex the database
$ reindexdb test
To reindex the table
foo and the index
bar in a database named
$ reindexdb --table foo --index bar abcd
