reindexdb is a utility for rebuilding indexes in a PostgreSQL database.
reindexdb is a wrapper around the SQL command REINDEX. 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:
-a
--all
Reindex all databases.
-s
--system
Reindex database's system catalogs.
-t table
--table table
Reindex table
only.
-i index
--index index
Recreate index
only.
[-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.
-q
--quiet
Do not display a response.
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
--password
Force password prompt.
In case of difficulty, see REINDEX 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 29.13, “The Password File” for more information.
