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.
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 -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.
Echo the commands that reindexdb generates and sends to the server.
Recreate index only. Multiple indexes can be recreated by writing
multiple -i switches.
Do not display progress messages.
Reindex database’s system catalogs.
Reindex schema only. Multiple schemas can be reindexed by writing
multiple -S switches.
Reindex table only. Multiple tables can be reindexed by writing
multiple -t switches.
Print detailed information during processing.
Print the reindexdb version and exit.
Show help about reindexdb command line arguments, and exit.
reindexdb also accepts the following command-line arguments for
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
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.
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
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).
In case of difficulty, see REINDEX(7) and psql 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.
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.
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
